Also remove SetStopOthers from the ThreadPlanCallFunction, because if the value you have doesn't match what is
in the EvaluateExpressionOptions the plan was passed when created it won't work correctly.

I ran this test 10 times successfully against Ubuntu 12.04 LTS x86_64
with lldb built with gcc 4.8.2 and July 2013 libedit.

1 - There were some outdated options being passed to clang
2 - There were some bad paths being passed as options
3 - The path to the main.cpp file ("/tmp/main.cpp") was wrong when the tests were being run, now we create a temp file
4 - Added a new ActionType::eNone to do nothing (no continue, step, or kill)

This change fixes up issues with specifying the size of the i386
register infos for FPU registers. The bug was that for the i386
register context, the size of the FPU registers were still being
computed based on the x86_64 FXSAVE structure.
This change permits the FPR_SIZE macro to optionally be defined
outside of RegisterInfos_i386.h, which RegisterContextLinux_i386.cpp
does properly. It redefines the FPR_i386 structure with all the
accessible parts that RegisterInfos_i386.h wants to see, which we had
not done before when we made the overall size of the structure
properly sized a recently.
This change also modifies POSIXThread to create a
RegisterContextLinux_i386 only when the host is 32-bit; otherwise, it
uses the RegisterContextLinux_x86_64, which works properly for 32-bit
and 64-bit inferiors on a 64-bit host.
I tested this debugging a Linux x86 exe on an x86 host (Ubuntu 13.10
x86), and debugging a Linux x86 exe and a Linux x86-64 exe on an
x86-64 host (Ubuntu 12.04 LTS). Those cases all worked.
Thanks to Matthew Gardiner who discoverd may key insights into
tracking down the issue. The motivation for this change and some of
the code originates from him via this thread:

We now write a 'q' to indicate to exit the IOHandlerProcessSTDIO::Run(), and a 'i' to interrupt the process. This should make this code safer to use in a signal handler function.

4-byte reserved area when reading the libBacktraceRecording API results.
Also, add a little logging about queues being created.

This fix changes thee x86 32-bit floating point register area to be
the proper size independent of the host platform.
Note as of this change list, this register context is not yet used
since selecting it exposes issues with watchpoint assertions.

These libraries became necessary recently to link properly.
I think they are needed everywhere non-Windows, but if they
end up breaking on a given platform, we can conditionalize this
further.

Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841
This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).
On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.
This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:
1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.
2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.
3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.
The net effect of this change on Linux is that the embedded python's
readline support will not exist.

Also fix the bug where lldb prints: "Got a connection and launched debugserver" rather
than the name of the process it actually launched.

class. If we try to unwind a stack frame to find a caller stack
frame, and we fail to get a valid-looking frame, AND if the UnwindPlan
we used is an assembly-inspection based UnwindPlan, then we should
throw away the assembly-inspection UnwindPlan and try unwinding with
the architectural default UnwindPlan.
This code path won't be taken if eh_frame unwind instructions are available -
lldb will always prefer those once it's off the zeroth frame.
The problem I'm trying to fix here is the class of unwind failures that
happen when we have hand-written assembly on the stack, with no eh_frame,
and lldb's assembly parser fails to understand the assembly. People usually
write their hand-written assembly to follow the frame-pointer-preserving
conventions of the platform so the architectural default UnwindPlan will
often work. We won't have the spill location for most of the non-volatile
registers if we fall back to this, but it's better than stopping the unwind
prematurely.
This is a bit of a tricky change that I believe is correct, but if we get
unwinds that go of into the weeds / unwind bogus frames at the end of the
stack, I'll need to revisit it.
