@rnk suggested on D70749 <https://reviews.llvm.org/D70749> to do a simple revert of D69477 <https://reviews.llvm.org/D69477>. That's what this is.


This reverts commit c3b06d0c393e533eab712922911d14e5a079fa5d <https://reviews.llvm.org/rGc3b06d0c393e533eab712922911d14e5a079fa5d>.

Reason for revert: Caused miscompiles when inserting assume for undef.

Fixes PR44154.
