> Make CTU a two phase analysis

At this point maybe it will be a three phase, as we might dump the ASTs/create 
index in phase 1 :)

I wonder whether this is the right approach. Not inlining a function can also 
introduce false positives. While I do see why we do not want to inline ALL 
functions upfront, I wonder if we actually want to inline small functions. The 
CSA already has heuristics like this, to always inline really small functions 
(defined by the number of nodes in the Cfg) despite other cut heuristics and it 
was found to improve the quality of the results overall. I think doing 
something similar for CTU might ultimately improve the precision of the 
analysis. What do you think?
