cmd/compile: finish GOEXPERIMENT=preemptibleloops repair
A newish check for branch-likely on single-successor blocks
caught a case where the preemption-check inserter was
setting "likely" on an unconditional branch.
Fixed by checking for that case before setting likely.
Also removed an overconservative restriction on parallel
compilation for GOEXPERIMENT=preemptibleloops; it works
fine, it is just another control-flow transformation.
