a72b31c79e This is some groundwork for filtering the language Exception
breakpoints, for instance on the class of the thrown object.

This change doesn't actually make that work, the part where we
extract the thrown object type from the throw site isn't done yet.

This provides a general programmatic "precondition" that you can add
to breakpoints to give them the ability to do filtering on the LLDB
side before we pass the stop on to the user-provided conditions & 
callbacks.

ede3193bbd Add a "force_kill" arg to Process::Destroy(). This is needed after
the changes in r233255/r233258.  Normally if lldb attaches to
a running process, when we call Process::Destroy, we want to detach
from the process.  If lldb launched the process itself, ::Destroy
should kill it.

However, if we attach to a process and the driver calls SBProcess::Kill()
(which calls Destroy), we need to kill it even if we didn't launch it
originally.

The force_kill param allows for the SBProcess::Kill method to force the
behavior of Destroy.

8ac06996bf Support for truncate/append on log files
Summary:
Presently, if a log file already exists, lldb simply starts overwriting bits of it, without
truncating or anything. This patch makes it use eFileOptionFileTruncate by default. It also adds
an --append option, which will append to the file without truncating. A test is included.

0641ca1a2d Remove ScriptInterpreterObject.
This removes ScriptInterpreterObject from the codebase completely.
Places that used to rely on ScriptInterpreterObject now use
StructuredData::Object and its derived classes.  To support this,
a new type of StructuredData object is introduced, called
StructuredData::Generic, which stores a void*.  Internally within
the python library, StructuredPythonObject subclasses this
StructuredData::Generic class so that it can addref and decref
the python object on construction and destruction.

Additionally, all of the classes in PythonDataObjects.h such
as PythonList, PythonDictionary, etc now provide a method to
create an instance of the corresponding StructuredData type.  For
example, there is PythonDictionary::CreateStructuredDictionary.
To eliminate dependencies on PythonDataObjects for external
callers, all ScriptInterpreter methods now return only
StructuredData classes

The rest of the changes in this CL are focused on fixing up
users of PythonDataObjects classes to use the new StructuredData
classes.

9fe00e52d3 Bulk of the infrastructure work to allow script commands to be backed by object instances in addition to free functions
This works by creating a command backed by a class whose interface should - at least - include

def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)

What works:
- adding a command via command script add --class
- calling a thusly created command

What is missing:
- support for custom help
- test cases

The missing parts will follow over the next couple of days

This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)

00b7f95b12 Fix handling of backslashes in Args parsing
Summary:
Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the
backslash itself is not removed from the argument, nor there is a way to escape the backslash
itself. This leads to surprising results:

"a b" c"   -> 'a b', 'c'  # Here we actually have an unterminated quote, but that is ignored
"a b\" c"  -> 'a b\" c'   # We try to escape the quote. That works but the backslash is not removed.
"a b\\" c" -> 'a b\\" c'  # Escaping the backslash has no effect.

This change changes quote handling to be more shell-like:
- single quotes and backquotes are literal and there is no way to escape the closing quote or
  anything else inside;
- inside double quotes you can use backslash to escape the closing quote and another backslash
- outside any quotes, you can use backslash to escape quotes, spaces and itself.

This makes the parsing more consistent with what the user is familiar and increases the
probability that pasting the command line from shell to the "process launch" command "just work".

df50f9440d Handle trailing spaces on "settings set" command more correctly
Summary:
Currently we have some settings which treat "\ " on settings set commands specially. E.g., it is
a valid way of specifying an argument of " " to a target. However, this fails if "\ " is the last
argument as CommandObjectSettingsSet strips trailing whitespace. This resulted in a surprising
argument of "\" to the target.

This patch disables the training whitespace removal at a global
level. Instead, for each argument type we locally determine whether whitespace stripping makes
sense. Currently, I strip whitespace for all simple object type except of regex and
format-string, with the rationale that these two object types do their own complex parsing and we
want to interfere with them as least as possible. Specifically, stripping the whitespace of a
regex "\ " will result in a (surprising?) error "trailing backslash". Furthermore, the default
value of dissasembly-format setting already contains a trailing space and there is no way for the
user to type this in manually if we strip whitespace.

560558eb7c Introduce the notion of "runtime support values"
A runtime support value is a ValueObject whose only purpose is to support some language runtime's operation, but it does not directly provide any user-visible benefit
As such, unless the user is working on the runtime support, it is mostly safe for them not to see such a value when debugging

It is a language runtime's job to check whether a ValueObject is a support value, and that - in conjunction with a target setting - is used by frame variable and target variable
SBFrame::GetVariables gets a new overload with yet another flag to dictate whether to return those support values to the caller - that which defaults to the setting's value

In that case, we want to copy the entire file into memory.  The code was looking for
a default byte size of 0 to indicate that the user had not provided a specific # of

d26a1e5060 Fixed the failing test:
./dotest.py -A x86_64 -C clang -v -t  -f TestImageListMultiArchitecture.test_image_list_shows_multiple_architectures

The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.

Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).

1cd5e921e1 Preparatory infrastructural work to support dynamically determining sizes of ObjC types via the runtime
This is necessary because the byte size of an ObjC class type is not reliably statically knowable (e.g. because superclasses sit deep in frameworks that we have no debug info for)
The lack of reliable size info is a problem when trying to freeze-dry an ObjC instance (not the pointer, the pointee)

This commit lays the foundation for having language runtimes help in figuring out byte sizes, and having ClangASTType ask for runtime help
No feature change as no runtime actually implements the logic, and nowhere is an ExecutionContext passed in yet

2501e5e2ea Modified LLDB to be able to lookup global variables by address.
This is done by adding a "Variable *" to SymbolContext and allowing SymbolFile::ResolveSymbolContext() so if an address is resolved into a symbol context, we can include the global or static variable for that address.

This means you can now find global variables that are merged globals when doing a "image lookup --verbose --address 0x1230000". Previously we would resolve a symbol and show "_MergedGlobals123 + 1234". But now we can show the global variable name.

The eSymbolContextEverything purposely does not include the new eSymbolContextVariable in its lookup since stack frame code does many lookups and we don't want it triggering the global variable lookups.

a487aa4cdb Three related changes to help:
The default help display now shows the alias collection by default, and hides commands whose named begin with an underscore.  Help is primarily useful to those unfamiliar with LLDB and should aim to answer typical questions while still being able to provide more esoteric answers when required.  To that latter end an argument to include the hidden commands in help has been added, and instead of having a help flag to show aliases there is now one to hide them.  This final change might be controversial as it repurposes the -a shorthand as the opposite of its original meaning.

The previous implementation of OutputFormattedHelpText was easily confused by embedded newlines.  The new algorithm correctly breaks on the FIRST newline or LAST space/tab before the target column count rather than treating all whitespace interchangeably.

Command interpreters now have the ability to specify help prologue text and a command prefix string.  Neither are used in the current LLDB sources but are required to support REPL-like extensions where LLDB commands must be prefixed and additional help text is required to explain how to access traditional debugging commands.
