[PATCH] D91718: [LV] Legalize scalable VF hints

[Cullen Rhodes via Phabricator via llvm-commits]

c-rhodes updated this revision to Diff 312819.
c-rhodes added a comment.

Address @fhahn's comments, changes:

- Clarify help message in `-force-target-supports-scalable-vectors` flag.
- `s/IgnoreUserVF/IgnoreScalableUserVF/g`
- Added `isSafeForAnyVectorWidth` to LAA that checks if the number of elements that can be operated on simultaneously is not bound. This is used in `computeFeasibleMaxVF` to skip the checks for whether the VF is safe given the dependence distance.
