Auto merge of #91224 - couchand:2021-11/avr-asm, r=Amanieu

Support AVR for inline asm! A first pass at support for the AVR platform in inline `asm!`. Passes the initial compiler tests, have not yet done more complete verification. In particular, the register classes could use a lot more fleshing out, this draft PR so far only includes the most basic. cc `@Amanieu` `@dylanmckay`
