	* config/mips/mips.c (mips_symbol_insns_1): Allow LEAs of
	SYMBOL_FORCE_TO_MEM constants.
	(mips_rtx_costs): Give a cost of 1 to force_to_mem_operands.
	(mips16_rewrite_pool_refs_info): New structure.
	(mips16_rewrite_pool_constant): New function, split out from...
	(mips16_rewrite_pool_refs): ...here.  Take a pointer to a
	mips16_rewrite_pool_refs_info structure rather than a pointer
	to a constant pool.  Force force_to_mem_operands into memory.
	(mips16_lay_out_constants): Update call to mips16_rewrite_pool_refs.
	* config/mips/predicates.md (force_to_mem_operand): New predicate.
	* config/mips/constraints.md (kf): New constraint.
	* config/mips/mips.md (*movdi_64bit_mips16): Add a d <- kf alternative.
	(*movsi_mips16): Likewise.
