Log:
	* Makefile.in (gtm-low.o): Don't depend on gtm-defines.h.
	* builtin-types.def: Don't include it.
	* c-common.c (handle_gtm_unknown_attribute): Stub out
	setting DECL_IS_GTM_UNKNOWN.
	* c-decl.c (merge_decls): Don't propogate it.
	* c-parser.c (c_parser_gtm): Remove decl.
	* c-typeck.c (c_finish_gtm_txn): Don't special-case for OpenMP;
	make that the only case.
	* cgraphbuild.c (prepare_gtm_clone): Use MAIN_NAME_P.  Use concat
	for resetting the assembler name.

	* gimple.h (struct gimple_statement_seq): Rename from 
	gimple_statement_omp.  Update all users.
	(is_gimple_gtm): New.
	* gtm-low.c (new_gtm_region): Remove type code.

	(set_gtm_pure_var, is_gtm_pure_var): Remove.
	(requires_barrier): Merge requires_read_barrier and
	requires_write_barrier; rewrite to match memory variables only.
