Saleem Abdulrasool 3985c8c646 sanitise sign comparisons
This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc.  This helps cleanup some of the warning
spew that occurs during builds.

Jim Ingham d80102e420 Add the ability to set python breakpoint commands from the SBBreakpoint & SBBreakpointLocation API's.
You can either provide the function name, or function body text.
Also propagate the compilation error up from where it is checked so we can report compilation errors.

Ed Maste 4e0999bc22 Implement ProcessMonitor::Kill for Linux
On FreeBSD ptrace(PT_KILL) is used to terminate the traced process
(as if PT_CONTINUE had been used with SIGKILL as the signal to be
delivered), and is the desired behaviour for ProcessPOSIX::DoDestroy.

On Linux, after ptrace(PTRACE_KILL) the traced process still exists
and can be interrogated.  It is only upon resume that it exits as though
it received SIGKILL.

As the Linux PTRACE_KILL behaviour is not used by LLDB, rename
BringProcessIntoLimbo to Kill, and change the implementation to simply
call kill() instead of using ptrace.

Thanks to Todd F for testing (Ubuntu 12.04, gcc 4.8.2).

Ed Maste af58e02d1c mips64: clean up register context storage
Store the gpr data in a DataBufferHeap and use a DataExtractor to
extract register values with appropriate endianness.  This avoids hard-
coding the register count, and with some further work would allow this
class to provide generic register context storage for any CPU.

On Linux, after ptrace(PTRACE_KILL) the traced process still exists

For now I'm committing only the FreeBSD change, until the Linux change
(review D3159) is successfully tested.

Jason Molenda a332978b2a lldb arm64 import.
These changes were written by Greg Clayton, Jim Ingham, Jason Molenda.

It builds cleanly against TOT llvm with xcodebuild.  I updated the
cmake files by visual inspection but did not try a build.  I haven't
built these sources on any non-Mac platforms - I don't think this
patch adds any code that requires darwin, but please let me know if
I missed something.

In debugserver, MachProcess.cpp and MachTask.cpp were renamed to
MachProcess.mm and MachTask.mm as they picked up some new Objective-C
code needed to launch processes when running on iOS.

Jim Ingham 6c8824d216 Wait for the reply from the 'D' detach packet before tearing down the debugger. Avoids a race
condition where we could end up killing debugserver (and thus the target) before it had a chance
to detach.
Also fix debugserver to send the OK AFTER it detaches to avoid the same race condition.

Todd Fiala 4339f3a434 Improve Elf object file UUID calculation performance.
This change makes significant improvements in the performance of
calculating a UUID within ObjectFileELF, and handles both running
processes and core files correctly. This does lazy evaluation of
UUID generation and caches the result when calculated.

Todd Fiala e373b68977 Fixed up intermittently failing tests to skip on Linux.
Also added 'import sys' on some tests that are using non-standard
unittest2.skipUnless blocks with code that is intended to do things
that we have more specializes @* attributes for.  These skip
conditions were failing to execute due to missing import, causing
darwin-only tests to run on Linux regardless.  Will file a bug for
that separately.

Greg Clayton fc03f8fcb6 A fix for: http://llvm.org/bugs/show_bug.cgi?id=19241

Ed Maste 03c9207c34 Update 'running threaded' messages after option parsing change
"Running multithreaded with n threads (from LLDB_TEST_THREADS)" is
incorrect in the common case, because the thread count is now obtained
from a --threads option, or a default of multiprocessing.cpu_count().

I left the messages in for now as there are some intermittent issues
that happen while running tests multithreaded and it may help in
triaging those.  We may wish to just remove them later on.

Greg Clayton 23f8c95a44 JITed functions can now have debug info and be debugged with debug and source info:
(lldb) b puts
(lldb) expr -g -i0 -- (int)puts("hello")

First we will stop at the entry point of the expression before it runs, then we can step over a few times and hit the breakpoint in "puts", then we can continue and finishing stepping and fininsh the expression.

Main features:
- New ObjectFileJIT class that can be easily created for JIT functions
- debug info can now be enabled when parsing expressions
- source for any function that is run throught the JIT is now saved in LLDB process specific temp directory and cleaned up on exit
- "expr -g --" allows you to single step through your expression function with source code
