96d58e64cf [ms-inline asm] Have the TargetParser callback to Sema to determine the size of
a memory operand.  Retain this information and then add the sizing directives
to the IR.  This allows the backend to do proper instruction selection.

f793fbc569 lit: Remove support for XTARGET.

970755e519 This patch is to fix radar://8426430. It is about llvm support of __builtin_debugtrap()
which is supposed to consistently raise SIGTRAP across all systems. In contrast,
__builtin_trap() behave differently on different systems. e.g. it raises SIGTRAP on ARM, and
SIGILL on X86. The purpose of __builtin_debugtrap() is to consistently provide "trap"
functionality, in the mean time preserve the compatibility with on gcc on __builtin_trap().

  The X86 backend is already able to handle debugtrap(). This patch is to:
  1) make front-end recognize "__builtin_debugtrap()" (emboddied in the one-line change to Clang).
  2) In DAG legalization phase, by default, "debugtrap" will be replaced with "trap", which
     make the __builtin_debugtrap() "available" to all existing ports without the hassle of
     changing their code.
  3) If trap-function is specified (via -trap-func=xyz to llc), both __builtin_debugtrap() and
     __builtin_trap() will be expanded into the function call of the specified trap function.
    This behavior may need change in the future.

  The provided testing-case is to make sure 2) and 3) are working for ARM port, and we
already have a testing case for x86.

974b190717 Use an export list when building JIT unittests. <rdar://problem/12473675>
When building with LTO, the internalize pass is hiding some global symbols

LTO to do that by default, but until that gets fixed, this change makes sure
that we export the necessary symbols for the tests to pass.

When merging stack slots, if StackColoring::remapInstructions gets a

the merged slot. This prevents the introduction of incorrect aliasing
information.

0c41d57b09 instcombine: Migrate strcpy optimizations
This patch migrates the strcpy optimizations from the simplify-libcalls pass
into the instcombine library call simplifier.  Note also that StrCpyChkOpt
has been updated with a few simplifications that were being done in the
simplify-libcalls version of StrCpyOpt, but not in the migrated implementation
of StrCpyOpt.  There is no reason to overload StrCpyOpt with fortified and
regular simplifications in the new model since there is already a dedicated
simplifier for __strcpy_chk.
