cmd/compile: make loop finder more aware of irreducible loops The loop finder doesn't return good information if it encounters an irreducible loop. Make a start on improving this, and set a function-level flag to indicate when there is such a loop (and the returned information might be flaky). Use that flag to prevent the loop rotater from getting confused; the existing code seems to depend on artifacts of the previous loop-finding algorithm. (There is one irreducible loop in the go library, in "inflate.go").
