Hi Melvin,

This patch does the following things:

 - It includes patch #813 from Sean O'Rourke

 - It fixes another bug in spill(), who was generating bad code

 - It adds a bunch of work using the control-flow graph, analyzing the 
exact places of the code where a variable is alive, and using this in 
order to improve the interference analysis. 

Incidentally, while tracking a memory bug, I added code to check the 
results of all malloc calls. I've left it there, since it shouldn't 

I am sending you this through bugs-parrot, as people on the IRC 
channel suggested.
