[OpenMP] Target directive host codegen.

This patch implements the outlining for offloading functions for code 
annotated with the OpenMP target directive. It uses a temporary naming 
of the outlined functions that will have to be updated later on once 
target side codegen and registration of offloading libraries is 
implemented - the naming needs to be made unique in the produced 
library.
