Sathya Gunasekaran 867cd0384b [api] Reland "Assign serial numbers when template infos are added to cache" 
Instead of assigning serial numbers when the template infos are
created, this patch creates serial numbers only when they are added to
cache.

This way only the ones that are first instantiated are allocated the
fast template cache. Previously, various accessors and methods that
would almost never get instantiated got assigned to the fast template
cache.
