    Set omp_requires_mask for dynamic_allocators.
    
    This is backport of a patch posted in
    https://gcc.gnu.org/pipermail/gcc-patches/2022-February/590655.html
    
    This patch fixes an issue that although gfortran accepts
    'requires dynamic_allocators', it does not set the omp_requires_mask
    accordingly.
    
    gcc/fortran/ChangeLog:
    
            * parse.c (gfc_parse_file): Set OMP_REQUIRES_DYNAMIC_ALLOCATORS
            bit in omp_requires_mask.
