Daniel Jasper 4431aa99ab Fix formatting of complex #if expressions. 
Before:
  #if !defined(AAAAAAAAAAAAAAAA) && (defined CCCCCCCC ||                         \
                                     defined DDDDDDDD) && defined(BBBBBBBB)

After:
  #if !defined(AAAAAAAAAAAAAAAA) && (defined CCCCCCCC || defined DDDDDDDD) &&    \
      defined(BBBBBBBB)

This fixes llvm.org/PR15828.

Reid Kleckner de0c26046d Un-revert the environ copy in ProgramTest after fixing it on OS X 
This was r180041 and r180046, which was reverted in r180066.
Re-committing this should fix the dragonegg bootstrap, which I presume
needs LD_LIBRARY_PATH to be propagated to the child.

Tested on Linux, Windows, and Mac OS 10.6.

Alexey Samsonov 068fc8ae6e Use zlib to uncompress debug sections in DWARF parser.

debug info sections compressed by ld.gold linker.

Jason Molenda 0f224d2cd4 Update the unwind_diagnose script to work correctly with both 
lldb-179 version numberings and the new lldb-300 version numberings.
Remove the pretense that someone might run this from the command
line; this is only used from within a live lldb debug session.  Fix
the loading so it can be loaded via "script import lldb.macosx" or
the script can be loaded individually like "command script import
unwind_diagnose.py"

Pekka Jaaskelainen 6f2f66b63f Refuse to (even try to) vectorize loops which have uniform writes, 
even if erroneously annotated with the parallel loop metadata.

Tim Northover 2ac2d4c59d AArch64: remove unnecessary check that RS is valid 
AArch64 always demands a register-scavenger, so the pointer should never be
NULL. However, in the spirit of paranoia, we'll assert it before use just in
case.

Jason Molenda 535ab8601f Add a new -a / --address argument to image show-unwind to get the 
unwind instructions for a function/symbol which contains that
address.

Update the unwind_diagnose.py script to use this instead of doing
image show-unwind by name to avoid cases where there are multiple
name definitions.

Jason Molenda caae381b35 Add a new python file to help diagnose backtrace failures in the field. 
It will be installed in the LLDB.framework and can be loaded with

  (lldb) script import lldb.macosx

after which a "unwind-diagnose" command will be registered.  Select
the thread which has a bad backtrace and run this command -- a lot
of information about the stack frames, and an alternate backtrace
algorithm, will be used.  The information will often be sufficient
for a remote person to figure out why the backtrace failed.

Argyrios Kyrtzidis 40bcfd71b6 When modifying an implicit instantiation with information from an explicit one, make sure to reset the "right brace" location. 
Otherwise the source range of the explicit instantiation may become invalid (begin location will be after the end location).

Jordan Rose 6e3cf2ba85 [analyzer] Model strsep(), particularly that it returns its input. 
This handles the false positive leak warning in PR15374, and also serves
as a basic model for the strsep() function.

Manman Ren 4a4970ec6a Struct-path aware TBAA: update getMostGenericTBAA 
The tag is of type TBAANode when flag EnableStructPathTBAA is off.

Move implementation of MDNode::getMostGenericTBAA to TypeBasedAliasAnalysis.cpp
since it depends on how to interprete the MDNodes for scalar TBAA and
struct-path aware TBAA.

Eric Christopher 04d4e9312c Move C++ code out of the C headers and into either C++ headers
