libgomp.texi: Update OpenMP implementation status
Commit Message
]I saw that the following now is implemented:
* requires: dynamic_allocators is now also works
(by assuming that it is supported, no longer giving 'sorry')
https://gcc.gnu.org/r12-6641-g450c85b81f4dd67bf6211d307afdc0f3c07ef44f
* in_reduction on target: Now also supported for Fortran
https://gcc.gnu.org/r12-4574-gd98626bf451dea6a28a42d953f7d0bd7659ad4d5
(I kept the "P" because of "nowait")
I also note – but did not change:
* omp_display_env runtime routine P Not inside target regions
I observe that OpenMP 5.2 added:
"When called from within a target region the effect is unspecified."
Thus, regarding this as bug fix, it could also be "Y".
Thoughts?
[Some output modifications are also part of the pending device-specific
ICV patch, https://gcc.gnu.org/pipermail/gcc-patches/2022-January/588728.html
thus, as that patch are not yet it, one can also argue for "P" in terms of
the output.]
Otherwise: OK?

Yes, we should say Y instead of P for it.

Yes.
