[flang][OpenMP] Generalize checks of loop construct structure (#170735)
For an OpenMP loop construct, count how many loops will effectively be
contained in its associated block. For constructs that are loop-nest
associated this number should be 1. Report cases where this number is
different.

Take into account that the block associated with a loop construct can
contain compiler directives.
