     x86: promote arguments to C functions according to the ABI (#7383)

     I don't think the x86-64 version is quite right, but this ought to be
     enough to pass cgrun071.

     This code is terrible and needs a complete refactor.  There's a lot of
     duplication, and we ought to be specifying the ABI in a much more
     abstract way (like LLVM).
