Chandler Carruth fca3f4021a Teach the new SROA a new trick. Now we zap any memcpy or memmoves which ... are in fact identity operations. We detect these and kill their partitions so that even splitting is unaffected by them. This is particularly important because Clang relies on emitting identity memcpy operations for struct copies, and these fold away to constants very often after inlining. Fixes the last big performance FIXME I have on my plate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165285 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-05 01:29:09 +00:00
