  Log Message:
  -----------
  [X86] In shrinkAndImmediate, place the new constant into the topological sort.

Revert the change to use APInt::isSignedIntN from
5ff5cf8e057782e3e648ecf5ccf1d9990b53ee90.

Its clear that the games we were playing to avoid the topological
sort aren't working. So just fix it once and for all.

Fixes PR48888.
