Log message:
	* config/v850/v850.h (MULDI3_LIBCALL, UCMPDI2_LIBCALL, CMPDI2_LIBCALL,
	NEGDI2_LIBCALL, INIT_TARGET_OPTABS, MASK_STRICT_ALIGN): Define.
	(PREDICATE_CODES): Include new predicates.
	(RTX_COSTS): Handle UMOD and UDIV.  Tune MULT for v850e.
	(TARGET_SWITCHES):  Add strict-align.
	(TARGET_STRICT_ALIGN): New.
	(MASK_DEFAULT, STRICT_ALIGNMENT):  Redefine.
	* config/v850/t-v850 (MULTILIB_OPTIONS, MULTILIB_DIRNAMES):
	Define.
	(LIB1ASMFUNCS): Add v850_negdi2, v850_cmpdi2, v850_ucmpdi2,
	v850_muldi3.
	* config/v850/lib1funcs.asm (L_callt_save_r2_r29, L_return_r2_r29,
	L_callt_save_r2_r31, L_return_r2_r31,
	L_save_all_interrupt): Change addi to add.
	(L_save_interrupt, L_return_interrupt): Rework.
	(__return_r31):  Correct .size directive.
	(mulsi3, divsi3, udivsi3, umodsi3, modsi3): Tune for v850e.
	(v850_negdi2, v850_cmpdi2, v850_ucmpdi2, v850_muldi3):
	New routines.
	* config/v850/v850.c (expand_prologue): Call
	gen_callt_save_interrupt, gen_callt_restore_all_interrupt,
	gen_callt_return_interrupt and gen_callt_save_all_interrupt.
	(reg_or_int9_operand): New predicate.
	(reg_or_const_operand): New routine.
	* config/v850/v850.md (return_interrupt): Changed from
	restore_interrupt.
	(callt_save_all_interrupt): Changed from save_all_interrupt_v850e.
	(callt_save_interrupt): Change save sequence.
	(callt_return_interrupt): New.
	(save_interrupt): Don't use runtime function for LONG_CALLS
	and TARGET_PROLOG_FUNCTION.
	(save_all_interrupt): Likewise.
	(mulsi3): Use new predicate.
	(moviscc): Disallow some combination of constants.
	Fix define_split for sasf insns, so that it will not generate bad
	code if operand0 and operand5 are the same.
	* config/v850/v850-protos.h: Prototype new predicates.
