Does GCC still implement it this way?
One concern I have is that this will be an ABI breaking change, and I'm not
certain how disruptive it will be. If GCC already made that change, it may be
reasonable for us to also break it without having to add ABI tags or something
special. But if these changes diverge us from GCC, that may require some extra
effort to mitigate.

We tend not to use top-level const on locals in the project as a matter of
style.

This DR is also about partial class specializations -- are changes not needed
in `Sema::getMoreSpecializedPartialSpecialization()` as well?
It'd be helpful to add the examples from the DR here to make sure they're
handled properly.
