  -----------
  [Utils] stripDebugifyMetadata - use cast<> instead of dyn_cast_or_null<> to avoid dereference of nullptr

The pointer is dereferenced immediately, so assert the cast is correct instead of returning nullptr

  Log Message:
  -----------
  [AArch64] isProfitableToHoist - remove nullptr test

User is dereferenced on the main codepath so the null test is likely superfluous
