@arsenm Thanks for the review.

> This is still requiring the TTI as a dependency, so I don't understand what this solves?

The TTI is currently used for two things:

- `getFlatAddressSpace` which is absolutely required to return a non-default value for the pass to be able to function
- `hasVolatileVariant` which enables the pass to handle additional cases. The default TTI implementation will return `false` which is good enough for many uses.

This change enables >95% of the functionality of this pass to be used with the default TTI.
