I/O Library. This file has compiler specifics for GCC as there is no

GCC - uses EFIAPI assembler. __asm__ calls GAS. __volatile__ makes sure the
compiler puts the assembler in this exact location. The complex GNUC
operations are not optimzed. It would be possible to also write these
with EFIAPI assembler.
We don't advocate putting compiler specifics in libraries or drivers but there
is no other way to make this work.
