[Driver][OpenMP] Add logic for offloading-specific argument translation.

Summary:
This patch includes support for argument translation that is specific of a given offloading kind. Additionally, it implements the translation for OpenMP device kinds in the gcc tool chain.

With this patch, it is possible to compile a functional OpenMP application with offloading capabilities with no separate compilation.
