Jakob Stoklund Olesen 8b560b8c48 Only check for PHI uses inside the current loop. 
Hoisting a value that is used by a PHI in the loop will introduce a
copy because the live range is extended to cross the PHI.

The same applies to PHIs in exit blocks.

Also use this opportunity to make HasLoopPHIUse() non-recursive.
