m*v*s*! 

This is a major milestone for class optimization---the old anyValue-based
system is no longer in use; the classification system has been wholly
rewritten.

The ticks in the sampling profiler are now where they should be, open to
further optimization with a much more solid foundation.

Much better than the 102 ticks that anyValue was taking some time ago!

A lot of time used to be spent compiling functions as well, a lot of which
was removed by previous commits, bringing us to:

 [C++]:
   ticks  total  nonlib   name
     50    5.9%   30.5%  node::contextify::ContextifyContext::CompileFunction(v8::FunctionCallbackInfo<v8::Value> const&)
     20    2.4%   12.2%  write
      9    1.1%    5.5%  node::native_module::NativeModuleEnv::CompileFunction(v8::FunctionCallbackInfo<v8::Value> const&)
      6    0.7%    3.7%  __pthread_cond_timedwait
      4    0.5%    2.4%  mmap

All of this work has simplified the output enough that it's obviated a slew
of other optimizations that can be done in future work, though a lot of that
may wait for TAMER, since performing them in XSLT will be difficult and not
performant; the compiler is slow enough as it is.
