Keith Randall 5045fdd8ff cmd/compile: fix containsUnavoidableCall computation
The previous algorithm was incorrect, as it reused the dominatedByCall
slice without resetting it. It also used the depth fields even though
they were not yet calculated.

Also, clean up a lot of the loop detector code that we never use.

Always compute depths. It is cheap.

Update #71868

Not really sure how to test this. As it is just an advisory bit,
nothing goes really wrong when the result is incorrect.
