X86: do not fold load instructions such as [V]MOVS[S|D] to other instructions when the destination register is wider than the memory load. These load instructions load from m32 or m64 and set the upper bits to zero, while the folded instructions may accept m128. rdar://12721174 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168710 91177308-0d34-0410-b5e6-96231b3b80d8
