  [Attributor][FIX] Use maximal access for dereferenceability deduction

While we can use range information when we derive dereferenceability we
must make sure to pick he right end of the range. Before we always went
with the minimal offset, which is not correct if we want to combine
the base dereferenceability with some offset. In that case it's the
maximum that gives the correct result.

  [Attributor][OpenMPOpt][FIX] Register simplification callbacks

Heap-2-stack and heap-2-shared can replace an allocation call with
something else. To avoid us deriving information from the allocator
implementation we register a simplification callback now that will
force us to stop at the call site. We probably should create the
replacement memory eagerly and return that instead though.
