5812f5d7a8 Add a fix for an issue where LCSSA would fail to insert undef's in some corner 
cases.  Ideally, this issue will go away in the future as LCSSA gets smarter
about which Phi nodes it inserts.

cb66ae964e Finish removal of EH usage from the Archive library. The REQUIRES_EH flag 
in lib/Bytecode/Archive/Makefile is now removed. One small step closer to
a smaller LLVM.

1d48a494a2 X86 target specific DAG combine: turn build_vector (load x), (load x+4), 
(load x+8), (load x+12), <0, 1, 2, 3> to a single 128-bit load (aligned and
unaligned).

e.g.

__m128 test(float a, float b, float c, float d) {
  return _mm_set_ps(d, c, b, a);
}

_test:
        movups 4(%esp), %xmm0

Low Level Virtual Machine (http://llvm.org/):

  DEBUG build with assertions.

instead of like this:

Also, add a place for vendor version info.

8f95262124 Switch to a very conservative heuristic for determining when loop-unswitching 
will be profitable.  This is mainly to remove some cases where excessive
unswitching would result in long compile times and/or huge generated code.

Once someone comes up with a better heuristic that avoids these cases, this
should be switched out.
