0f1b95f818 AMDGPU: Rework how private buffer passed for HSA 
If we know we have stack objects, we reserve the registers
that the private buffer resource and wave offset are passed
and use them directly.

If not, reserve the last 5 SGPRs just in case we need to spill.
After register allocation, try to pick the next available registers
instead of the last SGPRs, and then insert copies from the inputs
to the reserved registers in the progloue.

This also only selectively enables all of the input registers
which are really required instead of always enabling them.

This doesn't quite match how SC prints it, which doesn't put it in a
comment.
