Nadav Rotem 8d80452076 LICM uses AliasSet information to hoist and sink instructions. However, other passes, such as LoopRotate ...

may invalidate its AliasSet because SSAUpdater does not update the AliasSet properly.
This patch teaches SSAUpdater to notify AliasSet that it made changes.
The testcase in PR12901 is too big to be useful and I could not reduce it to a normal size.
