This patch adds the new-in-5.2 features table to the OpenMP Implementation
Status
chapter of libgomp.
It is based on appendix 5.1 and a mix of my wording and Jakub's wording,
used when he did the implemented-in-GCC-xx archeology.
( The entries should be/should remain aligned with the just-posted wwwdocs
patch,
https://gcc.gnu.org/pipermail/gcc-patches/2022-May/594865.html )
OK?
