* 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.
