Dylan McKay d2c33c4ecb [AVR] Add the pseudo instruction expansion pass
Summary:
A lot of the pseudo instructions are required because LLVM assumes that
all integers of the same size as the pointer size are legal. This means
that it will not currently expand 16-bit instructions to their 8-bit
variants because it thinks 16-bit types are legal for the operations.

This also adds all of the CodeGen tests that required the pass to run.
