cmd/compile: fix phi-function updates for preemptible loops
Previous code failed to account for particular control flow
involving nested loops when updating phi function inputs.
Fix involves:
1) remove incorrect shortcut
2) generate a "better" order for children in dominator tree
3) note inner-loop updates and check before applying
outer-loop updates.
Fixes #20675.
