cmd/compile/internal/ssa: prefer non-indexed stores on amd64
We sometimes generate code like this:
v473 = MOVQconst <uintptr> // constant..
v580 = MOVBstoreidx1 <mem> v1056 v473 v819 v491 // ..only used as an index
Rewrite indexed stores to non-indexed version, where possible.
This allows to eliminate const->register move, reducing codesize and lowering register pressure.
