* tc_mips.h (MAX_GPREL_OFFSET): Change it to the maximum allowed 

value, not the word beyond maximum.
	* tc_mips.c (macro_build_lui): Code cleanup.
	(macro): Reflect change to MAX_GPREL_OFFSET.
	(mips_ip): Check explicitly against S_EX_NONE.
	(my_get_SmallExpression): parse for %gp_rel, not %gprel.
	(md_apply_fix): Code cleanup.
