The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

ValueObjectPrinter could enter an infinite loop while trying to display an aptly formed ValueObject: a reference, with a child of some pointer type, such that the pointees chain ended up pointing back to some part of itself - a pointer to itself being the simplest such case
Fixed here by only setting a pointer depth when needed, and ensuring that we won't overflow and wrap the pointer depth when it's zero.

The alias test "exprf x 1234" expands to "expr -f x 1234" and is
expected to fail: it ends up trying to evaluate the invalid expression
void
$__lldb_expr(void *$__lldb_arg)
{
-f x 1234;
}
On FreeBSD LLDB ends up finding a static function f() in a math library,
and thus the error produced does not include "use of undeclared
identifier 'f'".
We will report failure to parse the expression in any case, so require
only that error message.

Part 1 changes PlatformLinux::CreateInstance to always create with
is_host=false; that method is only used as the plug-in creator method
associated with the remote-linux platform plugin, and should therefore
always be remote.
Part 1 patch by Steve Pucci.
Part 2: fix a test break on linux.
In test/functionalities/thread/thread_specific_break, when using gcc,
either C99 mode would need to be enabled, or the code would need to
change. I changed a couple loop variable definitions to conform
to pre-C99 to simplify testing the fix. The second issue was
the necessity to include -lpthread as a linker option in the Makefile.
Any issues with that part are due to me (Todd Fiala).

control to the user anyway. This was put in to handle monitors that would say there was no
stop reason when you first attached to them. But it broke the case where you hit a thread specific
breakpoint on many threads, but NOT the one specified in the breakpoint. I work around this
by only doing the junky override when the StopID is 0 - i.e. on first attach.
This commit also adds a test for thread specific breakpoints.

The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)
The SB API has also been improved to handle both types of formats, and a test case is added

test_convenience_registers_16bit_with_process_attach fails due to
pr18200. The test has a @expectedFailureFreeBSD decorator, but it
appears this does not catch a RuntimError exception raised in the test
infrastructure, so the test still reports failure. For now just skip
it.

This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.
Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

@skipIfRemote is used to decorate test cases that don't make sense to run remotely.
@skipIfRemoteDueToDeadlock indicates these tests need to be looked at and currently deadlock the running of the test suite when run on remote systems. These issues should be fixed soon.

A number of tests fail to build on FreeBSD because the test build script
defaults to libstdc++ for clang. On FreeBSD the libstdc++ is rather old
and libc++ should be used instead.
(These tests previously had an @expectedFailureFreeBSD decorator for
pr16696, the umbrella PR for the lack of threaded inferior support on
FreeBSD. The work to add that support will be committed soon.)

Fixed the test case for "test/functionalities/exec/TestExec.py" on Darwin.
The issue was breakpoints were persisting and causing problems. When we exec, we need to clear out the process and target and start fresh with nothing and let the breakpoints populate themselves again. This patch correctly clears out the breakpoints and also flushes the process so that the objects (process/thread/frame) give out valid information.

This commit reimplements the TypeImpl class (the class that backs SBType) in terms of a static,dynamic type pair
This is useful for those cases when the dynamic type of an ObjC variable can only be obtained in terms of an "hollow" type with no ivars
In that case, we could either go with the static type (+iVar information) or with the dynamic type (+inheritance chain)
With the new TypeImpl implementation, we try to combine these two sources of information in order to extract as much information as possible
This should improve the functionality of tools that are using the SBType API to do extensive dynamic type inspection

Extend DummySyntheticProvider to actually use debug-info vended children as the source of information
Make Python synthetic children either be valid, or fallback to the dummy, like their C++ counterparts
This allows LLDB to actually stop bailing out upon encountering an invalid synthetic children provider front-end, and still displaying the non synthetized ivar info

Use 32-bit register enums without gaps on 64-bit hosts.
Don't show 64-bit registers when debugging 32-bit targets.
Add psuedo gpr registers (ax, ah, al, etc.)
Add mmx registers.
Fix TestRegisters.py to not read ymm15 register on 32-bit targets.
Fill out and move gcc/dwarf/gdb register enums to RegisterContext_x86.h
