<pre>Of course we can run -strip-debug, but that's not the point. I am suggesting
that we need to reconsider the decision to completely remove versioning
support. In practice, this means that when using LTO you cannot mix different
versions of clang without risk of crashing the compiler.
Using the verifier to discard old metadata would be one solution. Basing that
decision on a version number seems like it would be a whole lot simpler and
safer.</pre>
