Sanjay Patel d7c702b451 [LoopStrengthReduce, x86] don't add cost for a cmp that will be macro-fused (PR35681) ... In the motivating case from PR35681 and represented by the macro-fuse-cmp test: https://bugs.llvm.org/show_bug.cgi?id=35681 ...there's a 37 -> 31 byte size win for the loop because we eliminate the big base address offsets. SPEC2017 on Ryzen shows no significant perf difference. Differential Revision: https://reviews.llvm.org/D42607 llvm-svn: 324289		2018-02-05 23:43:05 +00:00
