The ValueMapper used by various cloning utility maps MDNodes also.

e9c59711d3 Replace a big gob of old coalescer logic with the new CoalescerPair class.
CoalescerPair can determine if a copy can be coalesced, and which register gets
merged away. The old logic in SimpleRegisterCoalescing had evolved into
something a bit too convoluted.

4b722108e2 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.

e39fdbe118 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.

151d26d15d MorphNodeTo doesn't preserve the memory operands. Because we're morphing a node
into the same node, but with different non-memory operands, we need to replace
the memory operands after it's finished morphing.

9a526495e0 Some targets don't require the fencing MEMBARRIER instructions surrounding
atomic intrinsics, either because the use locking instructions for the
atomics, or because they perform the locking directly. Add support in the
DAG combiner to fold away the fences.

186b3d2606 If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata.
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

f175c5c828 Also convert SUBREG_TO_REG to a KILL when relevant, like the other subreg
instructions.

This does not affect codegen much because SUBREG_TO_REG is only used by X86 and
X86 does not use the register scavenger, but it prevents verifier errors.
