Adds -fdebug-dump-parsing-log in the new driver. This option is
semantically identical to -fdebug-instrumented-parse in f18 (the
former is added as an alias in f18).
As dumping the parsing log makes only sense for instrumented parses, we
set Fortran::parser::Options::instrumentedParse to True when
-fdebug-dump-parsing-log is used. This is consistent with f18. To
facilate tweaking the frontend based on the action being run,
setUpFrontendBasedOnAction in CompilerInvocation.cpp is introduced.
