Jakob Stoklund Olesen 011207a0ae When MachineLICM is hoisting a physical register after regalloc, make sure the ...

register is not killed in the loop.

This fixes 188.ammp on ARM where the post-ra scheduler would grab a register
that looked available but wasn't.

A testcase would be huge and fragile, sorry.
