x86 backend where instructions were not marked maystore/mayload, and perf issues where instructions were not marked neverHasSideEffects. It would be really nice if we could write patterns for copy instructions. I have audited all the x86 instructions down to MOVDQAmr. The flags on others and on other targets are probably not right in all cases, but no clients currently use this info that are enabled by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45829 91177308-0d34-0410-b5e6-96231b3b80d8
