We need to be able to set the static chain on a few calls within the
Go runtime, so expose this with __builtin_call_with_static_chain.

         * c-family/c-common.c (c_common_reswords): Add
         __builtin_call_with_static_chain.
         * c-family/c-common.h (RID_BUILTIN_CALL_WITH_STATIC_CHAIN): New.
         * c/c-parser.c (c_parser_postfix_expression): Handle it.
         * doc/extend.texi (__builtin_call_with_static_chain): Document it.

	* gcc.dg/cwsc0.c: New test.
	* gcc.dg/cwsc1.c: New test.

OK.
