Thrift TException does not properly define virtual what() method.

Summary:
Clients would elect to call the base class what() method instead of the derived version.  This results in
less than usable exceptions for debugging.

Reviewed By: Karl * mcslee

Test Plan:
Tested with local application in development.

Revert Plan:
revertible.
