Greg Clayton 2289fa4820 Added the ability to set the Platform path for a module through the SBModule 
interface.

Added a quick way to set the platform though the SBDebugger interface. I will
actually an a SBPlatform support soon, but for now this will do.

ConnectionFileDescriptor can be passed a url formatted as: "fd://<fd>" where
<fd> is a file descriptor in the current process. This is handy if you have
services, deamons, or other tools that can spawn processes and give you a
file handle.

Eli Friedman 4105ed1523 Make FastEmit_ri_ try a bit harder to succeed for supported operations; FastEmit_i can fail for non-Thumb2 ARM. Makes ARMSimplifyAddress work correctly, and reduces the number of fast-isel bailouts on non-Thumb ARM.

Rafael Espindola 6a85f9b42e Avoid some uses of .uleb128. This is a small speedup and more importantly 
lets this code be used when producing assembly code for old assemblers without

Chandler Carruth f9e7410468 Disable -Wnon-pod-memset for now while I try to reduce the false 
positives still further.

The plan is to:

1) Create a more targeted warning for memset of memory pointing at
   a type with virtual methods or bases where a vptr would be
   overwritten.
2) Consider turning the above warning back on by default.
3) Evaluate whether any false positives in the existing warning can be
   detected and white listed in the warning implementation.
4) If #3 lowers the noise floor enough, enable the full warning in -Wall
   or -Wextra.

Comments or suggestions welcome. Even more welcome are specific test
cases which trigger the warning and shouldn't.

Johnny Chen 0f023fa4af Add the Python rich comparison methods for SBBreakpoint, where GetID() returns 
the breakpoint ID and provides the semantics needed for '==' and '!='.  And
modify LLDBIteratorTestCase.lldb_iter_2() to use '==' between two SBBreakpoint's.
