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. Reviewed By: ABataev Differential Revision: https://reviews.llvm.org/D128550
