Prior this commit, yvec will reuse input variables from xvec which is sound because we assume that they are equal anyway. However, this reusing adds complexity to Picus. This commit removes the reusing, simplifying the codebase. The removal should also not affect performance, since SMT solvers are very good at dealing with equalities. This also allows modular verification to be programmed more straightforwardly.
…eridise#22) Previously, we added them during a constraint optimization pass as a part of the AST traversal. This is not ideal for many reasons. First, we only want to include the definitons once, but the AST traversal opens an opportunity to accidentally include them more than once (e.g. if we happen to have a rcmds as a subnode of another node). Second, it meant that we needed the pdef? parameter so that on alternative constraints, the prime definitions are omitted. The refactoring simply put the definition inclusion at the top-level, simplifying the optimization pass.
