  [flang] Detect and report parsing failure (#121349)

The flang-new driver doesn't check for the case of the parser failing to
consume the entire input file. This is of course never an ideal outcome,
and usually signals a need to improve error recovery, but it is better
for the compiler to admit failure rather than to silently proceed with
compilation of what may well be an incomplete parse tree.
