AVR: Add cost computation for some insn combine patterns.
gcc/
* config/avr/avr.cc (avr_rtx_costs_1) [PLUS]: Determine cost for
usum_widenqihi and add_zero_extend1.
[MINUS]: Determine costs for udiff_widenqihi, sub+zero_extend,
sub+sign_extend.
* config/avr/avr.md (*addhi3.sign_extend1, *subhi3.sign_extend2):
Compute exact insn lengths.
(*usum_widenqihi3): Allow input operands to commute.
