	* mips.c (mips_expand_epilogue): Emit blockage insn before call to
	save_restore_insns if no FP and GP will be restored.
	* abi64.h (LONG_MAX_SPEC): Check MIPS_ABI_DEFAULT and TARGET_DEFAULT,
	and define __LONG_MAX__ appropriately.  Add support for -mabi=X,
	-mlong64, and -mgp{32,64} options.
	* mips.c (mips_abi): Change type to int.
	* mips.h (enum mips_abi_type): Delete.
	(ABI_32, ABI_N32, ABI_64, ABI_EABI): Define as constants.
	(mips_abi): Change type to int.
