	* config/tc-mips.c (macro): For M_LI_SS, decide how to handle it
	based on contents of imm_expr and offset_expr, rather than
	mips_pic.  For M_LI_DD, decide how to handle it based on segment
	name of offset_expr, rather than mips_pic.
	(mips_ip): If g_switch_value < 4, use immediate values for 'l'.
	If g_switch_value < 8, use .rdata rather than .lit for 'L'.
