*	[X86] Optimization for replacing LEA with MOV at frame index elimination time	Zvi Rackover	2016-09-26	1	-0/+15
	Summary: Replace a LEA instruction of the form 'lea (%esp), %ebx' --> 'mov %esp, %ebx' MOV is preferable over LEA because usually there are more issue-slots available to execute MOVs than LEAs. Latest processors also support zero-latency MOVs. Fixes pr29022. Reviewers: hfinkel, delena, igorb, myatsina, mkuper Differential Revision: https://reviews.llvm.org/D24705 llvm-svn: 282385
