Antti-Ville Tuuainen Passes GSoC Final Evaluation

[dsimcha]

Congratulations, Antti-Ville!  This project creates a better 
implementation of precise GC heap scanning than anything that's 
been created so far for D.  The goal is to eventually integrate 
it into standard D distributions.  Any volunteers for beta 
testing?

Code:

https://github.com/Tuna-Fish/druntime/tree/gc_poolwise_bitmap

The code for this project is a fork of druntime.  The master 
branch was a failed (or less successful) experiment.  The version 
we're going with for integration is the gc_poolwise_bitmap branch.
