[PATCH] D12635: merge vector stores into wider vector stores and fix AArch64 misaligned access TLI hook (PR21711)

[Sanjay Patel via llvm-commits]

spatel updated this revision to Diff 34591.
spatel added a comment.

Patch updated based on Matt's feedback:

1. Use getStoreSize() rather than getSizeInBits().
2. I haven't found any interesting new test cases where this will fire because we're still quite limited in what we try to merge, so no new test cases vs. previous revision of this patch.
