Keith Randall 7735dc90ed [release-branch.go1.25] cmd/compile: don't rely on loop info when there are irreducible loops
Loop information is sketchy when there are irreducible loops.
Sometimes blocks inside 2 loops can be recorded as only being part of
the outer loop. That causes tighten to move values that want to move
into such a block to move out of the loop altogether, breaking the
invariant that operations have to be scheduled after their args.

Fixes #75595
