  -----------
  [IR] Fix assertion error in User new/delete edge case (#129914)

Fixes #129900

If `operator delete` was called after an unsuccessful constructor call
after `operator new`, we ran into undefined behaviour.
This was discovered by our malfunction tests while preparing an upgrade
to LLVM 20, that explicitly check for such kind of bugs.
