libgomp.texi: Add more to-be-implemented OpenMP 5.2 features / [wwwdocs] p.texi: Add more to-be-implemented OpenMP 5.2 features
Commit Message
I had a look at the OpenMP 5.2 changes and found some more,
which I think should be listed. Some were rather hidden, two
were only documented in the deprecate part.
I also added the 'begin declare target', which is a variant
to the delimited form of 'declare target' – the non-begin
variant is then deprecated in 5.1. (The begin variant permits
clauses, the other doesn't.)
OK? Comments?
Tobias
PS: For Fortran, 5.1 permitted with capture:
[!$omp end atomic]
namely: the 'end atomic' is optional.
gfortran has implemented this – but 5.2 now made it required again,
treating it as bug. I am not sure whether this should now also be
listed as 'deleted' feature or not. Hmm.

Fixes: Remove the last two items – they were already in the list (ups).
libgomp/libgomp.texi – forgot to update the default-map clause wording;
now again in sync with the html version.

Ok.
