Cherry Zhang 6fbdfe4804 cmd/compile: on PPC64, fold offset into some loads/stores only when offset is 4-aligned
On PPC64, MOVWload, MOVDload, and MOVDstore are assembled to a
"DS from" instruction which requiers the offset is a multiple of
4. Only fold offset to such instructions if it is a multiple of 4.

Fixes #36723.

"GOARCH=ppc64 GOOS=linux go build -gcflags=all=-d=ssa/check/on std cmd"
passes now.
