Johannes Doerfert bd756286d2 [OpenMP][FIX] Enforce a function boundary for a new data environment 
Whenever we enter a new OpenMP data environment we want to enter a
function to simplify reasoning. Later we probably want to remove the
entire specialization wrt. the if clause and pass the result to the
runtime, for now this should fix PR48686.
