  Log Message:
  -----------
  [Attributor] If provided, only look at simplification callbacks not IR

A simplification callback can mean that the IR value is modified beyond
the apparent IR semantics. That is, a `i1 true` could be replaced by an
`i1 false` based on high-level domain-specific information. If a user
provides a simplification callback we will not look at the IR but
instead give up if the callback returns a nullptr.

  [OpenMP] Simplify the ThreadStackTy for globalization fallback

With D106496 we can make the globalization fallback stack much simpler
and this version doesn't seem to experience the spurious failures and
deadlocks we have seen before.
