Jim Grosbach aae0a4bd87 Fix a memory leak in MachOObjectFile. 
MachOObjectFile owns a MachOObj, but never frees it. Both MachOObjectFile
and MachOObj want to own the MemoryBuffer, though, so we have to be careful
and give them each one of their own.

Thanks to Greg Clayton, Eric Christopher and Michael Spencer for helping
figure out what's going wrong here.

Benjamin Kramer ba11a9892c Follow up to 168711: It's safe to base this analysis on the found compare, just return the value for the right predicate.

Rafael Espindola 8778c28022 Merge function types in C. 
Among other differences, GCC accepts

  typedef int IA[];
  typedef int A10[10];
  static A10 *f(void);
  static IA  *f(void);
  void g(void) {
    (void)sizeof(*f());
  }

but clang used to reject it with:

  invalid application of 'sizeof' to an incomplete type 'IA' (aka 'int []')

The intention of c99's 6.2.7 seems to be that we should use the composite type
and accept as gcc does.

Doing the type merging required some extra fixes:
  * Use the type from the function type in initializations, even if an parameter
    is available.
  * Fix the merging of the noreturn attribute in function types.
  * Make CodeGen  handle the fact that an parameter type can be different from
    the corresponding type in the function type.

Evgeniy Stepanov f433cecf96 [msan] Fix getOriginForNaryOp. 
The old version failed on a 3-arg instruction with (-1, 0, 0) shadows (it would
pick the 3rd operand origin irrespective of its shadow).
    
The new version always picks the origin of the rightmost poisoned operand.

Benjamin Kramer aa598b3be6 misched: Recompute priority queue when DFSResults are updated. 
This was found by MSVC10's STL debug mode on a test from the test suite. Sadly
std::is_heap isn't standard so there is no way to assert this without writing
our own heap verify, which looks like overkill to me.

Justin Holewinski bc45119b44 Allow targets to prefer TypeSplitVector over TypePromoteInteger when computing the legalization method for vectors

Evgeniy Stepanov 62b5db9361 [msan] Transform memcpy and memset to library calls. 
This was already done for memmove, where it is required for correctness.
This change improves performance by avoiding copyingthe same memory twice.
Also, the library functions are given __msan_ prefix to prevent instcombine
pass from converting them back to intrinsics.
