Commited patch from Björn Steinbrink:
Summary:
Different range metadata can lead to different optimizations in later
passes, possibly breaking the semantics of the merged function. So range
metadata must be taken into consideration when comparing Load
instructions.

Thanks!

Generate native unwind info on Win64

This patch enables LLVM to emit Win64-native unwind info rather than
DWARF CFI.  It handles all corner cases (I hope), including stack
realignment.

Because the unwind info is not flexible enough to describe stack frames
with a gap of unknown size in the middle, such as the one caused by
stack realignment, I modified register spilling code to place all spills
into the fixed frame slots, so that they can be accessed relative to the
frame pointer.

Patch by Vadim Chugunov!

Revert "Replace Execution Engine's mutex with std::recursive_mutex."

This reverts commit 1f502bd9d7d2c1f98ad93a09ffe435e11a95aedd, due to
GCC / MinGW's lack of support for C++11 threading.

It's possible this will go back in after we come up with a
reasonable solution.

[X86] Add ISel patterns to select SSE3/AVX ADDSUB instructions.

This patch adds ISel patterns to select SSE3/AVX ADDSUB instructions
from a sequence of "vadd + vsub + blend".

Example:

///
typedef float float4 __attribute__((ext_vector_type(4)));

float4 foo(float4 A, float4 B) {
  float4 X = A - B;
  float4 Y = A + B;
  return (float4){X[0], Y[1], X[2], Y[3]};
}
///

Before this patch, (with flag -mcpu=corei7) llc produced the following
assembly sequence:
  movaps  %xmm0, %xmm2
  addps   %xmm1, %xmm2
  subps   %xmm1, %xmm0
  blendps $10, %xmm2, %xmm0


With this patch, we now get a single
  addsubps  %xmm1, %xmm0
