b2bd7e89e6 [TBAA] Fix handling of mixed TBAA (path-aware and non-path-aware TBAA).
This fix simply ensures that both metadata nodes are path-aware before
performing path-aware alias analysis.

This issue isn't normally triggered in LLVM, because we perform an autoupgrade
of the TBAA metadata to the new format when reading in LL or BC files. This
issue only appears when a client creates the IR manually and mixes old and new
TBAA metadata format.

This fixes <rdar://problem/16760860>.
