[OpenMP] Ensure testing for versions 4.5 and default - Part 2 Many OpenMP Clang tests do not RUN for version 4.5 and the default version. This second patch in the series handles test cases which require updation in CHECK lines along with adding RUN lines for the default version. It involves updating line number of pragmas.
