    X86: change MOV64ri64i32 into MOV32ri64

    The MOV64ri64i32 instruction required hacky MCInst lowering because it was
    allocated as setting a GR64, but the eventual instruction ("movl") only set
a
    GR32. This converts it into a so-called "MOV32ri64" which still accepts a
    (appropriate) 64-bit immediate but defines a GR32. This is then converted
to
    the full GR64 by a SUBREG_TO_REG operation, thus keeping everyone happy.
