This syncs the libgomp.texi implementation status to the webpage,
i.e. adding a few new items + marking some as 'supported'.
It also fixes a couple of bugs and adds links providing more details
for two items (a PR link as in libgomp.texi and a section in the manual).
Comments? Suggestions? If not, I will commit it tomorrow.
Current version: https://gcc.gnu.org/projects/gomp/
General suggestions about this page - like what to add, split off,
move around are also welcome. (Likewise comments to
Tobias
PS: The patch assumes that's Sandra's intervening-code support patch is
applied (should happen in a few hours).
PPS: The GCC 14 release notes still need to be updated to match the
current support. Alas, that's an on going theme as features keep getting
added :-)
