This corrects the MI annotations for the stack adjustment following the __chkstk invocation. We were marking the original SP usage as a Def rather than Kill. The (new) assigned value is the definition, the original reference is killed. Adjust the ISelLowering to mark Kills and FrameSetup as well. This partially resolves PR27480. llvm-svn: 267361
