[llvm] r182991 - X86: change MOV64ri64i32 into MOV32ri64

[Joe Groff]

+def MOV32ri64 : Ii32<0x88, AddRegFrm, (outs GR32:$dst), (ins
i64i32imm:$src),
+                     "", [], IIC_ALU_NONMEM>, Sched<[WriteALU]>;
+

This looks wrong. 0x88 isn't an AddReg opcode; 0x89, 0x8A, etc. are
different opcodes:

I'm seeing miscompiles in the JIT after this patch.
