[DAG] OptLevelChanger - fix uninitialized variable analyzer warning (PR44471)

Browse Source 
Ensure that OptLevelChanger::SavedFastISel is initialized in the constructor.

This should be NFC - as the equivalent 'same opt level' early-out is used in the destructor as well, so SavedFastISel is only actually referenced in the general case.
