I'm a little skeptical about making TBAA more aggressive.  In most situations, 
we're probably talking about tiny performance gains, and currently there's no 
good way to check whether a codebase suffers from type punning issues (either 
with compile-time analysis or runtime instrumentation).  Probably LLVM itself 
does, but we have no way of knowing.
