- X86 unfolding should check if the instructions being unfolded has memoperands. If there is no memoperands, then it must assume conservative alignment. If this would introduce an expensive sse unaligned load / store, then unfoldMemoryOperand etc. should not unfold the instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107509 91177308-0d34-0410-b5e6-96231b3b80d8
