Allocate alias registers for an alias group while trying to minimize the
number of needed aliases. That is, if the allocated GPRs for the group
are (partially) consecutive, only allocate aliases to fill-in the gaps.
For example:
sam ..., @{r1.x, r5.z, r1.z}, ...
only needs a single alias:
alias.tex.b32.0 r1.y, r5.z
sam ..., r1.x, ...
Also, try to reuse allocations of previous groups. For example, this is
relatively common:
sam ..., @{r2.z, 0}, @{0}
Reusing the allocation of the first group for the second one gives this:
alias.tex.b32.0 r2.w, 0
sam ..., r2.z, r2.w
