avr-protos.h (avr_output_addr_vec_elt): Prototype.

	* config/avr/avr-protos.h (avr_output_addr_vec_elt): Prototype.
	* config/avr/avr.c (jump_tables_size): New variable.
	(function_prologue): Initialize it as 0.
	(function_epilogue): Add it to function_size.
	(avr_output_addr_vec_elt): New function.  Count words in jump
	tables in jump_tables_size.  Move code ...
	* config/avr/avr.h (ASM_OUTPUT_ADDR_VEC_ELT): ... from here.
	Call avr_output_addr_vec_elt instead.
	* config/avr/avr.md (tablejump): Remove disabled define_expand.
