This patch adds a way to fetch breakpoint metadatas as a serialized
`Structured` Data format (JSON). This can be used by IDEs to update
their UI when a breakpoint is set or modified from the console.

This is one of the most expensive tests and runs for nearly half a minute on
my machine. Beside this test just doing a lot of work by iterating 15k times on
one ValueObject (which seems to be the point), it also runs this for every
debug info variant which doesn't seem relevant to just iterating ValueObject.
This marks it as no_debug_info_test to only run one debug info variation
and cut down the runtime to around 7 seconds on my machine.
1. Added a dedicated completion to class `CommandObjectTypeFormatterDelete`

TestCompletion is randomly failing on some bots. The error message however states
that the computed completions actually do contain the expected pid we're
looking for, so there shouldn't be any test failure.
The reason for that turns out to be that complete_from_to is actually used
for testing two different features. It can be used for testing what the
common prefix for the list of completions is and *also* for checking all the
possible completions that are returned for a command. Which one of the two
things should be checked can't be defined by a parameter to the function, but
is instead guessed by the test method instead based on the results that were
returned. If there is a common prefix in all completions, then that prefix
is searched and otherwise all completions are searched.
For TestCompletion's pid test this behaviour leads to the strange test failures.
If all the pid's that our test LLDB can see have a common prefix (e.g., it
can only see pids [123, 122, 10004, 10000] -> common prefix '1'), then
complete_from_to check that the common prefix contains our pid, which is
always fails ('1' doesn't contain '123' or any other valid pid). If there
isn't a common prefix (e.g., pids are [123, 122, 10004, 777]) then
complete_from_to will check the list of completions instead which works correctly.
This patch is fixing this by adding a simple check method that doesn't
have this behaviour and is simply searching the returned list of completions.
This should get the bots green while I'm working on a proper fix that fixes
complete_from_to.
The Length, AbbrOffset and Values fields of the debug_info section are
optional. This patch helps remove them and simplify test cases.

TestStandardUnwind uses the full absolute path to a set of C/C++ files as the test case name, which in turn is used in the name of a log file. When the source file is long, and the directory where log files are stored is also long, this causes an OSError because the log filename is too long.

This test appears to have never worked on Linux but it seems none of the current
bots ever ran this test as it required enabling compiler-rt (otherwise it
would have just been skipped).
This just copies over the XFAIL decorator that are already on all other sanitizer
tests.
psutil isn't reall a dependency of the test suite so this shouldn't be
unconditionally be imported here. Instead just check for the process name
by looking for the "a.out" string to get the bots green again.
Breakpad will always have a UUID for binaries when it creates minidump files. If an ELF files has a GNU build ID, it will use that. If it doesn't, it will create one by hashing up to the first 4096 bytes of the .text section. LLDB was not able to load these binaries even when we had the right binary because the UUID didn't match. LLDB will use the GNU build ID first as the main UUID for a binary and fallback onto a 8 byte CRC if a binary doesn't have one. With this fix, we will check for the Breakpad hash or the Facebook hash (a modified version of the breakpad hash that collides a bit less) and accept binaries when these hashes match.

Rename the existing expectedFailure to expectedFailureIfFn to better
describe its purpose and provide an overload for
unittest2.expectedFailure in decorators.py.
The search for the complete class definition can also produce entries
which are not of the expected type. This can happen for instance when
there is a function with the same name as the class we're looking up
(which means that the class needs to be disambiguated with the
struct/class tag in most contexts).
Previously we were just picking the first Decl that the lookup returned,
which later caused crashes or assertion failures if it was not of the
correct type. This patch changes that to search for an entry of the
correct type.

Some of the test methods were already skipped because of an unexpected
packet. The test started failing after it was expanded. Skip the whole
test with reproducers so we don't have to add the decorator for every
method.
expect_expr currently can't verify the children of the result SBValue.
This patch adds the ability to check them. The idea is to have a CheckValue
class where one can specify what attributes of a SBValue should be checked.
Beside the properties we already check for (summary, type, etc.) this also
has a list of children which is again just a list of CheckValue object (which
can also have children of their own).
The main motivation is to make checking the children no longer based
on error-prone substring checks that allow tests to pass just because
for example the error message contains the expected substrings by accident.
I also expect that we can just have a variant of `expect_expr` for LLDB's
expression paths (aka 'frame var') feature.

Summary:
This effectively reverts r188124, which added code to handle
(DW_AT_)declarations of structures with some kinds of children as
definitions. The commit message claims this is a workaround for some
kind of debug info produced by gcc. However, it does not go into
specifics, so it's hard to reproduce or verify that this is indeed still a
problem.
Having this code is definitely a problem though, because it mistakenly
declares incomplete dwarf declarations to be complete. Both clang (with
-flimit-debug-info) and gcc (by default) generate DW_AT_declarations of
structs with children. This happens when full debug info for a class is
not emitted in a given compile unit (e.g. because of vtable homing), but
the class has inline methods which are used in the given compile unit.
In that case, the compilers emit a DW_AT_declaration of a class, but
add a DW_TAG_subprogram child to it to describe the inlined instance of
the method.
Even though the class tag has some children, it definitely does not
contain enough information to construct a full class definition (most
notably, it lacks any members). Keeping the class as incomplete allows
us to search for a real definition in other modules, helping the
-flimit-debug-info flow. And in case the definition is not found we can
display a error message saying that, instead of just showing an empty
struct.
