greg 9b62efc830 Fix conditional parsing

greg 95b773de7f Compilation sequence 
-move all steps of the llvm IR compilation process into the binary
 2017-09-19 22:10:57 -07:00
greg 923566c4e9 Get rid of println's for token/ast debugging 
Instead just explicitly stick them into the returned string.

soon, so I can't have any side effects
