mips.c (mips_use_dfa_pipeline_interface): Delete.

	* config/mips/mips.c (mips_use_dfa_pipeline_interface): Delete.
	(TARGET_SCHED_USE_DFA_PIPELINE_INTERFACE): Define to hook_int_void_1.
	* config/mips/3000.md: Add copyright notice.  Remove automota and
	function units; use generic ones instead.  Only define reservations
	for things that are different from generic.md.  Extend each clause
	to include r3900.
	* config/mips/{4000,4100,4300,4600,5000,6000,generic}.md: New files.
	* config/mips/mips.md: Include them. Remove define_function_units.
	(alu, imuldiv): New automata and units.
