[OpenMP] Code generation for target exit data directive Summary: This patch adds support for the target exit data directive code generation. Given that, apart from the employed runtime call, target exit data requires the same code generation pattern as target enter data, the OpenMP codegen entry point was renamed and reused for both. Reviewers: hfinkel, carlo.bertolli, arpith-jacob, kkwli0, ABataev Subscribers: cfe-commits, fraggamuffin, caomhin Differential Revision: http://reviews.llvm.org/D17369 llvm-svn: 267814

[OpenMP] Use fopenmp prefix for all options introduced by the offloading implementation. Summary: This patch changes the options used by offloading to start with -fopenmp instead of -fomp. This makes the option naming more consistent and materializes a suggestion by Richard Smith in http://reviews.llvm.org/D9888.
