Log:
gcc/
	* config/mips/mips.h (BASE_INSN_LENGTH, NOP_INSN_LENGTH): New macros.
	* config/mips/mips.c (mips_symbol_insns, mips_address_insns)
	(mips_const_insns, mips_split_const_insns, mips_load_store_insns)
	(mips_idiv_insns): Update the comments to say that the returned
	instruction counts are in units of BASE_INSN_LENGTH.
	(mips_adjust_insn_length): Multiply the mips_load_label_num_insns
	by BASE_INSN_LENGTH rather than 4.  Add the jump separately,
	using 2 rather than 4 as the length of indirect MIPS16 and
	microMIPS jumps.  Use NOP_INSN_LENGTH rather than 4 as the
	length of a NOP.  Don't divide MIPS16 lengths by 2.
	(mips16_split_long_branches): Assume a branch is long if the
	length is greater than 4 rather than 8.
	* config/mips/mips.md (length): Give MIPS16 lengths directly,
	rather than multiplying them by 2.  Multiply instruction counts
	by BASE_INSN_LENGTH rather than 4.
	(*jump_mips16, tls_get_tp_mips16_<mode>)
	(*tls_get_tp_mips16_call_<mode>): Divide lengths by 2.
