Use DomTree in MachineSink to sink over diamonds.
According to a previous FIXME comment we now not only look at MBB
successors, but also handle code sinking past them:
x = computation
if () {} else {}
use x
The instruction could be sunk over the whole diamond for the
if/then/else (or loop, etc), allowing it to be sunk into other blocks
after that.
Modified test added in r204522, due to one spill less present.
Minor fixes in comments.
Patch provided by Jonas Paulsson. Reviewed by Hal Finkel.
