* config/avr/avr.c: Include ggc.h.
(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.
