OK.  I've noted the name lookup issue (see my other patch) and how it
impacts on the overall front-end perfomance.  I would like to extend
the existing timevar framework to include time-report for at least:

   * class and object layout
   * template instantiation
   * overloading resolution

Reducing the "everything is a tree" paradigm to the struct minimum
should enable considerable correctness and performance gains also.

Thanks a lot!
