Log:

	* hard-reg-set.h (target_hard_regs): Add x_accessible_reg_set
	and x_operand_reg_set.
	(accessible_reg_set, operand_reg_set): New macros.
	* reginfo.c (init_reg_sets): Initialize accessible_reg_set and
	operand_reg_set.
	(saved_accessible_reg_set, saved_operand_reg_set): New variables.
	(save_register_info): Save them.
	(restore_register_info): Restore them.
	(init_reg_sets_1): Limit operand_reg_set to accessible_reg_set.
	Remove NO_REGS registers from operand_reg_set.  Treat members
	of operand_reg_set as fixed.
	* recog.c (general_operand): Check operand_reg_set rather than
	NO_REGS.
	(register_operand, nonmemory_operand): Likewise.
	* varasm.c (make_decl_rtl): Always use DECL_MODE as the mode of
	register variables.  Check accessible_reg_set and operand_reg_set.
	* config/mips/mips.c (mips_conditional_register_usage): Remove
	inaccessible register from accessible_reg_set, rather than just
	making them fixed.

gcc/testsuite/
	* gcc.target/mips/mips.exp (mips-dg-options): Make -mno-dsp
	imply -mno-dspr2.
	* gcc.target/mips/no-dsp-1.c: New test.
	* gcc.target/mips/soft-float-1.c: Likewise.
