This patch ports the fopenmp-host-ir-file-path flag from Clang to Flang-new, this flag is added by the driver to the device pass when doing two phase compilation (device + host).

This flag is then applied to the module when compiling during the OpenMP device phase. This file can then be utilised during lowering of the OpenMP dialect to LLVM-IR, which allows the device and host to maintain 1:1 mapping of OpenMP metadata for variables during lowering via the OpenMPIRBuilders loadOffloadInfoMetadata facilities (which is used for declare target and I believe target regions as well).
