gpu-compute, hsail: pass GPUDynInstPtr to getRegisterIndex()

for HSAIL an operand's indices into the register files may be calculated
trivially, because the operands are always read from a register file, or are
an immediate.

for machine ISA, however, an op selector may specify special registers, or
may specify special SGPRs with an alias op selector value. the location of
some of the special registers values are dependent on the size of the RF
in some cases. here we add a way for the underlying getRegisterIndex() method
to know about the size of the RFs, so that it may find the relative positions
of the special register values.
