Add "mayHaveSideEffects" and "neverHasSideEffects" flags to some instructions. I based what flag to set on whether it was already marked as "isRematerializable". If there was a further check to determine if it's "really" rematerializable, then I marked it as "mayHaveSideEffects" and created a check in the X86 back-end similar to the remat one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45132 91177308-0d34-0410-b5e6-96231b3b80d8
