Why would anyone care about the performance of an access to an
un-initialized variable?  Rather than attempting to insure their
diagnosis, and hopeful subsequent removal the specified code?

Personally, see no value in producing faster garbage; although do
see substantial value in producing compiled code which is strictly
consistent with the specified program and native target behavior,
regardless of its portability.
