A large portion of AVR instructions are simply "aliases", or "special cases" of other instructions.
For example, cli is defined as bclr 7 (in `AVRInstrInfo.td):
def : InstAlias<"cli", (BCLRs 7)>;
When calling llc and generating an assembly file, or llvm-mc -show-encoding, the instruction printer always prints out the least general instruction.
For example, cli -> bclr 7
This hurts readability greatly, and it is also making the unit tests more difficult because we must replace all instruction aliases by what they actually alias.
