	(tmp_reg_rtx): Declare with GTY.
	(zero_reg_rtx): Likewise.
	(ldi_reg_rtx): Remove.
	(avr_override_options): Initialize zero_reg_rtx and
	ldi_reg_rtx.
	(avr_init): Remove.
	Include gt-avr.h.
	* config/avr/avr.h (LDI_REG_REGNO): Remove.
	Remove externs for tmp_reg_rtx, zero_reg_rtx, and ldi_reg_rtx.
