Committed to gomp-4_0-branch in r222278:

commit fd3add90d38d5f1b38c9cb557404542b6383b2b0

    Add BUILT_IN_GOACC_KERNELS_INTERNAL
    
    ..., a variant of the GOACC_kernels builtin.  This variant does not call the
    function passed as function pointer, and therefore is less of an optimization
    barrier than the original variant.
    
    The purpose of this variant is to allow the introduction of the GOACC_kernels
    call before splitting off the region body into a function (something that is
    currently done simultaneously).
