The AVR back-end really needs improvement:
        ldi r18,lo8(1)
        ldi r19,hi8(1)
.L3:
        std Y+2,r19
        std Y+1,r18
        ldi r24,lo8(99)
        ldi r25,hi8(99)

here r25 and r19 are the same, 0.

Other than that, we need to estatimate the cost of adding/subtracting/comparing
of integers > WORD_SIZE better.
