[PATCH] D137341: [VectorCombine] widen a load with subvector insert

[Sanjay Patel via Phabricator via llvm-commits]

spatel updated this revision to Diff 473724.
spatel added a comment.

Rebased with a new test (last test/diff in the test file) that includes addrspacecast. This will crash if we don't re-insert a cast.

I think we could reduce the wordiness by calling `CreatePointerCast()` rather than `CreateBitCastOrAddrSpaceCast()`, but I'd make that change to the existing code too to keep these in sync (assuming that works in the other transform).
