[PATCH] D117803: [PowerPC] Update handling of splat loads for v4i32/v4f32/v2i64 to require non-extending loads.

[Amy Kwan via Phabricator via llvm-commits]

amyk updated this revision to Diff 402066.
amyk added a comment.

Address Nemanja's review comments:

- Add a comment as to why extending loads are allowed for i8/i16 types (because they're not legal types)
- Change the cast to LoadSDNode to dyn_cast, add early exits
