Solution unifies interface of RegionCodeGenTy type to allow insert runtime-specific code before/after main codegen action defined in CGStmtOpenMP.cpp file. Runtime should not define its own RegionCodeGenTy for general OpenMP directives, but must be allowed to insert its own (required) code to support target specific codegen. llvm-svn: 264700
