A couple of failing tests which do have reliable syntax workarounds, so added their fixes as TODOs for now.

I think this should be all for now for refactoring the conditionals and the expr_pass (incidental). We now need to extensively use eval_expr in binops, assignments and statemnet processing.

Pull Request Overview

This PR refactors conditional expression handling by extracting condition evaluation logic from the functions module into a dedicated expression module. The refactoring improves support for complex conditional expressions including boolean operations, comparisons, and unary operations.

• Moved conditional evaluation logic from functions_pass.py to a new expr module
• Added comprehensive support for boolean operations (and, or) with proper short-circuiting
• Enhanced comparison operations with type normalization and pointer handling
