Jake Bailey 27ff0f249c cmd/compile/internal/ssa: eliminate string copies for calls to unique.Make
unique.Make always copies strings passed into it, so it's safe to not
copy byte slices converted to strings either. Handle this just like map
accesses with string(b) as keys.

This CL only handles unique.Make(string(b)), not nested cases like
unique.Make([2]string{string(b1), string(b2)}); this could be done in a
followup CL but the map lookup code in walk is sufficiently different
than the call handling code that I didn't attempt it. (SSA is much
easier).

Fixes #71926
