Jakob Stoklund Olesen 031432f9ad Speed up LiveIntervals::shrinkToUse with some caching. ...

Blocks with multiple PHI successors only need to go on the worklist
once.  Use a SmallPtrSet to track the live-out blocks that have already
been handled.  This is a lot faster than the two live range check we
would otherwise do.

Also stop recomputing hasPHIKill flags.  Like RenumberValues(), it is
conservatively correct to leave them in, and they are not used for
anything important.

Target

Fix the code creating VZEXT_LOAD so that it creates the right memoperand. Issue spotted in -debug output. I can't think of any practical effects at the moment, but it might matter if we start doing more aggressive alias analysis in CodeGen.
