mips-protos.h (m16_usym8_4, [...]): Delete.

	* config/mips/mips-protos.h (m16_usym8_4, m16_usym5_4): Delete.
	* config/mips/mips.h (mips_entry, mips_string_length): Delete.
	(CONSTANT_POOL_BEFORE_FUNCTION, ASM_OUTPUT_POOL_EPILOGUE): Undefine.
	* config/mips/mips.c (struct mips16_constant): Renamed from struct
	constant.  Propogate change throughout file.
	(struct machine_function): Remove insns_len.
	(mips_string_length, mips16_strings, string_constants): Delete.
	(mips_classify_symbol): Return SYMBOL_CONSTANT_POOL for LABEL_REFs
	when generating mips16 code.  Remove special mips16 treatment of
	string constants.
	(mips_symbolic_constant_p): Allow mips16 constant pool accesses
	to have the form LABEL+CONSTANT.
	(mips_symbolic_address_p): Fix comment.
	(m16_usym8_4, m16_usym5_4): Delete.
	(mips_output_function_epilogue): Remove mips16 string handling.
	(mips_output_mi_thunk): Call mips16_lay_out_constants.
	(mips_select_section, mips_encode_section_info): Remove mips16
	string handling.
	(struct mips16_constant_pool): New.
	(add_constant): Take a mips16_constant_pool structure.  Keep pool
	sorted into order of ascending mode size.  Keep track of the highest
	possible start address, taking padding and the masking of the base PC
	value into account.
	(dump_constants_1): New function, split out from dump_constants.
	Handle vector constants.  Use gen_consttable_{int,float} rather than
	separate functions for each mode.
	(dump_constants): Simplify.  Use GET_MODE_ALIGNMENT.  Use gen_align
	rather than separate functions for each alignment.
	(mips_find_symbol): Delete.
	(mips16_insn_length): New function, split out from
	mips16_lay_out_constants.
	(mips16_rewrite_pool_refs): New function.
	(mips16_lay_out_constants): Rework. Remove string handling.
	Always create an inline constant pool.
	* config/mips/mips.md (UNSPEC_CONSTTABLE_INT, UNSPEC_CONSTTABLE_FLOAT)
	(UNSPEC_ALIGN): New constants.
	(UNSPEC_CONSTTABLE_[QHSD]I, UNSPEC_CONSTTABLE_[SD]F): Delete.
	(UNSPEC_ALIGN_[248]): Delete.
	(consttable_int, consttable_float, align): New patterns.
	(consttable_[qhsd]i, consttable_[sd]f, align_[248]): Delete.
