[PATCH] D52307: [LoopRotate] Fix lifetime handling.

An alloca can have multiple associated lifetime start/ends.  Inlining routinely generates code like that, unrolling generates code like that, etc.  And stack coloring knows how to handle such code.

Granted, the way the intrinsic is specified makes everything related to it pretty confusing.
