[AVR] Add disassembly tests for supported instructions 

The disassembler of the AVR backend is incomplete: most instructions do
not correctly disassemble yet.

This patch is the first in a series to add disassembly support to the
AVR backend. It starts with adding disassembler tests for instructions
that already disassemble correctly.
