AVR: target/85624 - Fix non-matching alignment in clrmem* insns.
The clrmem* patterns don't use the provided alignment information,
hence the setmemhi expander can just pass down 0 as alignment to
the clrmem* insns.
PR target/85624
gcc/
* config/avr/avr.md (setmemhi): Set alignment to 0.
gcc/testsuite/
* gcc.target/avr/torture/pr85624.c: New test.
