This PR fixes a Fortran syntax violation in the OpenMP default mapper
naming convention. The suffix .omp.default.mapper contains dots which
are invalid in Fortran identifiers, causing failures when mappers are
written to and read from module files. The fix changes the suffix to
_omp_default_mapper which uses underscores instead of dots, complying
with Fortran syntax rules.
Key changes:
- Changed OmpDefaultMapperName constant from .omp.default.mapper to
_omp_default_mapper
- Added GetUltimate() calls in mapper symbol resolution to properly
handle symbols across module boundaries
- Added new test case verifying default mappers work correctly when
defined in a module and used in consuming programs
This fixes#168336.
