Peter Klausler be6bc6a1e5 [flang] Better recovery from errors in a loop control (#117025) ...

When there's an error in a DO statement loop control, error recovery
isn't great. A bare "DO" is a valid statement, so a failure to parse its
loop control doesn't fail on the whole statement. Its partial parse ends
after the keyword, and as some other statement parsers can get further
into the input before failing, errors in the loop control can lead to
confusing error messages about bad pointer assignment statements and
others. So just check that a bare "DO" is followed by the end of the
statement.
