Remove the uninitialized instance variable verbose mode warning

This speeds up all instance variable access, even when not in
verbose mode.  Uninitialized instance variable warnings were
rarely helpful, and resulted in slower code if you wanted to
avoid warnings when run in verbose mode.

Implements [Feature #17055]
