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.

Summary:
This patch adds logic to create jobs for OpenMP offloading actions by:
- tuning the jobs result information to use the offloading prefix even for (device) linking actions.
- replacing the device inputs of the host linking jobs by a linker script that embed them in the right sections.

Summary:
This patch adds a new specialized action builder to create OpenMP offloading actions. The specialized builder is added to the action builder already containing the CUDA specialized builder.
OpenMP offloading dependences between host and device actions (expressed with OffloadActions) are different that what is used for CUDA:
- Device compile action depends on the host compile action - the device frontend extracts the information about the declarations that have to be emitted by looking into the metadata produced by the host frontend.
- The host link action depends on the device link actions - the device images are embedded in the host binary at link time.

Summary: This patch adds new logic to create the necessary tool chains to support offloading for OpenMP. The OpenMP related options are checked and the tool chains created accordingly. Diagnostics are emitted in case the options are illegal or express unknown targets.
