[PATCH] D115329: [LoopVectorize] Pass a vector type to isLegalMaskedGather/Scatter

[Rosie Sumpter via Phabricator via llvm-commits]

RosieSumpter added a comment.

- Moved code which checks if masked gathers/scatters are legal for the given vector width to `forceScalarizeMaskedGather/Scatter` for X86
- Pass VF to `isScalarWithPredication` so that we are consistently passing a vector type to `isLegalMaskedGather/Scatter`
- Add minimum vscale attribute to the necessary AArch64 tests
- Remove changes to X86 tests (X86 behaviour is now unchanged by this patch)
