Detailed Description

Container to pass LLVM IR runtime values or constants related to the number of teams and threads with which the kernel must be launched, as well as the trip count of the loop, if it is an SPMD or Generic-SPMD kernel.

These must be defined in the host prior to the call to the kernel launch OpenMP RTL function.
