hsail, gpu-compute: remove doGm/SmReturn add completeAcc

we are removing doGmReturn/doSmReturn from the GM/LM pipes respectively,
and adding completeAcc() implementations for the HSAIL mem ops. the behavior
in doGmReturn/doSmReturn is dependent on HSAIL and HSAIL mem ops, however the
completion phase of memory ops in machine ISA can be very different, even
amongst individual machine ISA mem ops. so we remove this functionality from
the pipeline and allow it to be implemented by the individual instructions.
