Keith Randall 44a6f817ea cmd/compile: fix write barrier coalescing
We can't coalesce a non-WB store with a subsequent Move, as the
result of the store might be the source of the move.

There's a simple codegen test. Not sure how we might do a real test,
as all the repro's I've come up with are very expensive and unreliable.

Fixes #71228
