emit-rtl.c (get_first_nonnote_insn, [...]): New functions.

	* emit-rtl.c (get_first_nonnote_insn, get_last_nonnote_insn): New
	functions.
	* rtl.h (get_first_nonnote_insn, get_last_nonnote_insn): Declare.
	* avr/avr.c (avr_output_function_epilogue): Use above to determine
	function size.
	* pa/pa.c (pa_output_function_prologue): Likewise.
