This documents two more OpenMP (5.0) routines, omp_pause_resource and
omp_pause_resource_all.
Comments, remarks, suggestions - to the patch or the documentation in
general?

PS: When looking at it, I found an issue in the spec with regards to a
new constant (post TR12, hence, not added here) and the missing
unspecified behavior when invoked from within a target region; that's
now tracked as OpenMP spec issue #3793.
PPS: Still to be documented routines: omp_target_memcpy* and the
places/affinity routines. (Plus OMPT, interop and TR11/TR12/... but
those have to be implemented first.)libgomp.texi: Document omp_pause_resource{,_all}
libgomp/ChangeLog:
* libgomp.texi (Runtime Library Routines): Document
omp_pause_resource and omp_pause_resource_all.
