[PATCH] D88432: [InstCombine] Fix pr47668

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

This is missing alive link.
I think the fix is wrong, based solely on the fact that it is huge.
I would think the fix should be:

- if the shift amount is a variable, check that it is not undef
- if it is a constant, sanitize undef elts to 0

Am i wrong?
