	Take the comparison's icode as an argument, not the function's fcode.
	(mips_expand_compare_builtin): New function.  Rename existing function
	to mips_expand_scalar_compare_builtin.
	(mips_expand_scalar_compare_builtin, mips_expand_4s_compare_builtin)
	(mips_expand_ps_compare_builtin): Use the new functions.  Take the
	comparison's icode as an argument, not the builtin's fcode.
