- Split `getSmallestAndWidestTypes` into two functions. `collectAllElementTypesInLoop` now iterates over every instruction in the loop and collects a list of the element types found, which is used later by `canWidenLoopWithScalableVectors` to disable scalable vectorization if any of the types are illegal. `getSmallestAndWidestTypes` now only returns the min & max widths found in the list of element types.
- Moved the `Ty->isIntegerTy(1)` check into `isElementTypeLegalForScalableVector`
- Added a test which stores an loop invariant i128 value to a variant address.
