[flang][OpenMP] Detect BLOCK construct through lookahead (#150617)
Avoid parsing the entire ExecutionPartConstruct in either the strictly-
or the loosely-structured block parser only to discard it when it's not
BLOCK (or is BLOCK) respectively. Doing so was not incorrct, but in
pathological cases (like Fujitsu 0981_0034) the recursive parsing can
take a very long time.
Instead, detect the presence of BLOCK first (via a simple lookahead),
and fail immediately if necessary.
