0c927a80fe Use ValueMap instead of DenseMap. 
The ValueMapper used by various cloning utility maps MDNodes also.

777c025ad8 We are missing opportunites to use ldm. Take code like this: 
void t(int *cp0, int *cp1, int *dp, int fmd) {
  int c0, c1, d0, d1, d2, d3;
  c0 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  c1 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  /* ... */
}

It code gens into something pretty bad. But with this change (analogous to the
X86 back-end), it will use ldm and generate few instructions.

e618e80a13 Do not do tail calls to external symbols. If the 
branch turns out to be ARM-to-Thumb or vice versa
the linker cannot resolve this.  8120438.

If this optimization is going to be useful we probably
need a compiler flag "assume callees are same architecture"
or something like that.

be50ef88bd Revert r106263, "Fold the ShrinkDemandedOps pass into the regular DAGCombiner pass,"... it was causing both 'file' (with clang) and 176.gcc (with llvm-gcc) to be miscompiled.

414eb48a14 When using libcall expansions for the atomic intrinsics, the explicit 
MEMBARRIER fences aren't necessary for ARM. Tell the combiner to fold them
away.
