clang-p2996/clang/test/OpenMP/target_map_codegen_25.cpp
Joseph Huber 1fff116645 [OpenMP] Change OpenMP code generation for target region entries 
This patch changes the code we generate to enter a target region on the
device. This is in-line with the new definition in the runtime that was
added previously. Additionally we implement this in the OpenMPIRBuilder
so that this code can be shared with Flang in the future.
