Starting on 3.  This is going to be a PTX transform that performs allocation and
manages spill code.  I will also add a stand alone program.

There is a preliminary version of 3 checked in in r282.  This should be updated 
such
that registers are given the correct type.  A graph coloring allocator can 
probably
resuse much of the same code.

Updated this so that registers now have the correct types.  I am leaning 
against doing a graph coloring allocator at this point at least, but I am going 
to keep this open in case someone else wants it.
