[flang] Fix source line continuation in potential macro calls (bugzilla 46768)
ClosedPublic

Summary

The prescanner looks for implicit continuation lines when
there are unclosed parentheses at the end of a line, so that
source preprocessing macro references with arguments that span
lines are recognized. The condition that determines this
implicit continuation has been put into a predicate member
function and corrected to apply only when the following line
is source (not a preprocessing directive, comment, &c.).

Fixes bugzilla #46768.
