iris.h (CTORS_SECTION_ASM_OP,DTORS_SECTION_ASM_OP, [...]): Use Pmode == DImode rather than TARGET_LONG64.
* config/mips/iris.h (CTORS_SECTION_ASM_OP,DTORS_SECTION_ASM_OP,
dtors_section): Use Pmode == DImode rather than TARGET_LONG64.
* config/mips/mips.c (override_options): Allow -mlong64 and
-mint64 with -mips2 or less.
* config/mips/mips.h (MASK_LONG64): Fix comment.
(POINTER_SIZE): Use Pmode == DImode rather than TARGET_LONG64.
(Pmode): Make Pmode the smaller of longs or gp registers.
* invoke.texi: Note the new size for pointers.
