mips.h (mips_output_conditional_branch): New function.

mips.h (mips_output_conditional_branch): New function.

	* mips.h (mips_output_conditional_branch): New function.
	(mips_adjust_insn_length): Likewise.
	(ASSEMBLER_SCRATCH_REGNUM): New macro.
	(ADJUST_INSN_LENGTH): Likewise.
	* mips.c (print_operand): Add `F' and `W' for floating-point
	comparison opcodes.
	(machine_dependent_reorg): Adjust MIPS16 code; instruction-lengths
	are now in bytes.
	(mips_adjust_insn_length): New function.
	(mips_output_conditional_branch): New function.
	* mips.md (length): Adjust attribute definition to handle
	conditional branches.  	Change lengths to bytes, rather than
	instructions throughout.  Remove length attribute from
	instructions whose length is four bytes, and rely on the default
	instead.
	(dslot): Fix typo in comment.
	Reword conditional branch patterns to use
	mips_output_conditional_branch.
