[0/6] OpenMP 5.0: Fortran "declare mapper" support

  This patch series implements "declare mapper" support for Fortran,
following on from the C and C++ support for same in the currently
in-review series posted here:

  https://gcc.gnu.org/pipermail/gcc-patches/2022-March/591973.html

Further commentary on individual patches. Tested with offloading to NVPTX.

OK? (Pending rework of the patch series it depends on?)

Thanks,

Julian
