  -----------
  [InstCombine] Re-queue users after freezeOtherUses rewrites their operands (#202306)

`freezeOtherUses()` rewrites dominated uses to a single frozen copy, but
does not re-queue the rewritten users. Any fold enabled by the rewrite
is therefore left for the next InstCombine iteration, which breaks the
expected single-iteration fixpoint and requires
`instcombine-no-verify-fixpoint` in the affected tests.

Re-queue each rewritten user and its users so the newly exposed folds
are visited in the same iteration.
