In order to fold calls based on high-level knowledge and control flow
tracking it helps to expose the information as a runtime call. The
logic: `!SPMD && getTID() == getMasterTID()` was used in various places
and is now encapsulated in `__kmpc_is_generic_main_thread`. As part of
this rewrite we replaced eager computation of arguments with on-demand
computation, especially helpful if the calls can be folded and arguments
don't need to be computed consequently.
