commit 0a63a142294e43addbb832fc247da362dd2561ea

    openmp: BUILT_IN_GOMP_ENABLE_PINNED_MODE
    
    Rework the GOMP_enable_pinned_mode call so that it works on powerpc where
    the old way gave a local call.
    
    gcc/ChangeLog:
    
            * omp-builtins.def (BUILT_IN_GOMP_ENABLE_PINNED_MODE): New.
            * omp-low.cc (omp_enable_pinned_mode): Use
            BUILT_IN_GOMP_ENABLE_PINNED_MODE.
