6e2dcdb1 - Fix implicit truncation of `select` non-bool vector conditions (#166279)

Fix implicit truncation of `select` non-bool vector conditions (#166279) Fixes #164018. The problem is that we're unable to do an implicit conversion sequence on a template deduced argument, so the current vector templates can't reconcile `vector<int, 4>` with `vector<bool, Sz>`. This PR separates the vector templates into size-specific ones, getting rid of the `Sz` deduction and allowing for the implicit conversion to be done.
