[AVR] Use 1-byte alignment for all data types
This was an oversight in the original backend data layout.
The AVR architecture does not have the concept of unaligned loads - all
loads/stores from all addresses are aligned to one byte.
Discovered in avr-rust issue #64
https://github.com/avr-rust/rust/issues/64
Patch By Gergo Erdi.
