    OpenMP: Small fortran/intrinsic.texi + libgomp.texi update
    
    Some followup to the OpenMP 5.2 version bump - and marking some features
    as partially implemented: uses_allocators (only predefined allocators),
    'declare mapper' (only C/C++, some but few loose ends), map iterator
    (C/C++ only - and several loose ends, most fixed by approved patches
    that still have to land after minor modifications).
    
    gcc/fortran/ChangeLog:
    
            * intrinsic.texi (OpenMP Modules OMP_LIB and OMP_LIB_KINDS): Link
            also to OpenMP 6.0, move 'partially supported' to the end of the
            list of OpenMP versions. Mark 'omp_lock_hint_...' and
            'omp_atv_sequential' constants as deprecated.
    
    libgomp/ChangeLog:
    
            * libgomp.texi (OpenMP Implementation Status): Add missing '@tab';
            claim initial partial support for 'declare mapper',
            'uses_allocators', and map iterators.
