I think we can use the code that lowers `hlfir.<intrinsic>` into openmp loops
at the point the `hlfir.<intrinsic>`s are lowered into `fir.call`s into the
flang rt library. We should have a check for whether we should use the generic
lowering or the openmp loop lowering (using the `shouldUseWorkshareLowering`
function) and then for the supported intrinsics lower it to openmp loops
instead of the rt call.
Another option is to have another pass which runs before the pass that does the
`fir.call` lowering and that pass takes care of the intrinsics we support.
Even if we use the first approach we should still probably have a separate
compilation unit for the collection of those. This way it should not interfere
much with the existing code and should be easy to integrate.
