* sh.h (NORMAL_MODE): If interrupt handler and TARGET_FMOVD,
	this is FP_MODE_DOUBLE .
	* sh.c (ra.h): #include.
	(push_regs): Add second parameter.  Changed all callers.
	If necessary, set fpscr before saving floating point registers.
	(calc_live_regs): If interrupt handler and TARGET_FMOVD, always
	do saves / restores with SZ == 1.
	(sh_expand_prologue): If interrupt handler, don't use gen_toggle_sz.
	(sh_expand_epilogue): Likewise.  For TARGET_FMOVD, if floating point
	registers are being restored, restore FPSCR only after restoring them.
