[Patch] OpenMP: Add omp_in_explicit_task to omp_runtime_api_call

When adding a new OpenMP routine, also omp_runtime_api_call needs
to be adapted - to get proper error like:

error: OpenMP runtime API call ‘omp_in_explicit_task’ in a region with ‘order(concurrent)’ clause

OK for mainline?

Tobias

PS: This routine was added in commit r13-3258-g0ec4e93fb9fa5e9d2424683c5fab1310c8ae2f76

PPS: I have not fully checked but I think it should be up to date; at least all
other recent additions include updates to that omp-low.cc function and at some point
I had checked it for completeness.
