The answer to the first question is in the comment above the function. It seems
this is needed for debugging and other stuff. 

Perhaps the search over the variants is not needed or can be made more
efficient?

In any case, it may be worth it to ask the question in the gcc@ mailing list,
CCing the C++ maintainers, which you can find in the MAINTAINERS file. Not many
people read bugzilla.
