Anchor some Clara vtables into the cpp file

Browse Source 
Anchoring the vtables does 2 things
1) Fixes some instances of `-Wweak-vtables`
2) Decreases code size and linker pressure

However, there are still some unanchored ones, and thus we have
to keep suppressing `-Wweak-vtables` warning for Clang.
