Only define QT_FASTCALL on x86_32
The __fastcall calling convention is silently ignored on other
architectures. The GNU attribute regparm is allowed but doesn't
make sense on x86_64. On other architectures, the attribute isn't
supported at all.
This fixes building with clang for MinGW/ARM and ARM64.
