Tony Gutierrez 844fb845a5 gpu-compute, hsail: make the PC a byte address, not an instruction index
currently the PC is incremented on an instruction granularity, and not as an
instruction's byte address. machine ISA instructions assume the PC is a byte
address, and is incremented accordingly. here we make the GPU model, and the
HSAIL instructions treat the PC as a byte address as well.
