cmd/compile, simd/archsimd: add VPSRL immeidate peepholes
Before this CL, the simdgen contains a sign check to selectively enable
such rules for deduplication purposes. This left out `VPSRL` as it's
only available in unsigned form. This CL fixes that.
It looks like the previous documentation fix to SHA instruction might
not had run go generate, so this CL also contains the generated code for
that fix.
There is also a weird phantom import in
cmd/compile/internal/ssa/issue77582_test.go
This CL also fixes that
The trybot didn't complain?
