Operations are divided into 3 categories:
- Load/Store ops including prefixed.
- Load/Store ops including prefixed, with alignment requirements
  for their non-prefixed version.
- Non-prefixed Load/Store.

We first check if a non-prefixed instruction can be emitted
and if so will emit that instead while making sure to check
for its alignment (if needed).
