avr.c (out_shift_with_cnt): Use AS2 macro.

	* config/avr/avr.c (out_shift_with_cnt): Use AS2 macro.
	Correct insn length if shift count is a memory operand.
	* config/avr/avr.md: New define_peephole2 to use *reload_inqi.
	(*iorhi3_clobber): Change lo8 to hi8.
	(zero_extendhisi2): Change %B0 to %A1.
	(ashlhi3, ashrhi3): Correct insn length.
	(andhi3, abssf2, extendqisi2, extendhisi2): Change "cc"
	from "clobber" to "set_n" in some alternatives.
