The introduction in r14-3488-ga62c8324e7e31a of OMP_STRUCTURED_BLOCK (to
diagnose invalid intervening code) caused a regression rejecting the valid use
of the Fortran CONTINUE statement to end a collapsed loop.
This patch fixes the incorrect error checking in the OMP lowering pass. It also
fixes a check in the Fortran front end that erroneously rejects a similar
statement in an ordered loop.
