I applied a fix for decode_reg_name.  CallingConv::ID is just an integer, as
such returning it by reference makes no sense.  It was a silliness in the
llvm-gcc code and I don't want to reintroduce it, so those bits are no good.
I will try to build an ARM cross-compiler here to understand the rest better.
This might take a few days.

Ciao, Duncan.
