Adding Q suffixes to FXSAVE/FXRSTOR did break the 32-bit build. Don't go
back though, as the hand-coded 0x48 there weren't quite right either for
the 32-bit case (they might well cause confusion when looking at the
disassembly). Instead arrange for the compiler to DCE respective asm()-s,
by short-c
