re PR target/50465 ([avr] Use insn attribute to depict if and how instruction lengths have to be adjusted)

	PR target/50465
	* config/avr/avr-protos.h (output_reload_insisf): Don't pass insn.
	* config/avr/avr.md (*reload_insi, *reload_insf): Change call to
	output_reload_insisf.
	(adjust_len): Set default to "no".
	Remove alternative "yes".  Add alternatives: "mov8", "mov16",
	"mov32", "ashlqi", "ashrqi", "lshrqi", "ashlhi", "ashrhi",
	"lshrhi", "ashlsi, "ashrsi", "lshrsi".
	(*movqi, *movhi, *movsi, *ashlqi3, ashlhi3, ashlsi3,

	*ashrhi3_const, *ashrsi3_const, *lshrqi3, lshrhi3, *lshrhi3_const,
	*lshrsi3_const): Set attribute "adjust_len".
	* config/avr/avr.c (output_reload_insisf): Remove parameter "insn".
	(output_movsisf): Don't pass insn to output_reload_insisf.
	(adjust_insn_length): Handle new alternatives to adjust_len.
	Remove handling of ADJUST_LEN_YES.  Clean-up code.
