The "rotl<mode>3" expanders (mode \in {HI,SI,DI}) violates synopsis by
using 4 operands instead of 3. This runs in ICE in top of
optabs.c:maybe_gen_insn.

The right way to do this is to use match_dup, not match_operand. So
the fix is obvious.

Regenerated avr-gcc and run against avr testsuite:

gcc.target/avr/torture/pr41885.c generates these patterns
