* config/mips/mips.c: Various formatting fixes.

	(override_options): Resync -mtune handling with gas.
	(mips_issue_rate): Rearrange like mips_use_dfa_pipeline_interface.
	* config/mips/mips.h: More formatting fixes.
	(mips_abi): Move declaration.
	* config/mips/mips.md (exception_receiver): Add mode to
	unspec_volatile.
