Saiyedul Islam eaa341fbea [OpenMP] Ensure testing for versions 4.5 and default - Part 1 
Many OpenMP Clang tests do not RUN for version 4.5 and the default
version. This first patch in the series only handles test cases
which do not require any modifications in the CHECK lines after
adding RUN lines for default version.
