[committed] Emit sorry on most requires clauses

[committed] Emit sorry on most requires clauses

[Jakub Jelinek]

Hi!

Similarly, the parsing here is implemented, but we don't do anything with it
later on (mainly propagate to the runtime library and filter the available
devices to the selected subset).

So, this patch again emits a sorry on it for now.

Bootstrapped/regtested on x86_64-linux and i686-linux, committed to trunk.

	* c-parser.c (c_parser_omp_requires): Call sorry_at on requires
	clauses other than atomic_default_mem_order.

	* parser.c (cp_parser_omp_requires): Call sorry_at on requires
	clauses other than atomic_default_mem_order.

	* c-c++-common/gomp/requires-1.c: Prune not supported yet messages.
	* c-c++-common/gomp/requires-2.c: Likewise.
	* c-c++-common/gomp/requires-4.c: Likewise.
