955344e175 C++: Inline a predicate that contains CPs 
The `overflows` predicate had quite severe Cartesian products. We didn't
see them in practice because magic saved us, but we can't rely on magic
in the future, so it seems better to inline this predicate.

Tuple counts and speed look good both before and after.

- Remove post-dominance requirement. It was really just hiding good
  results.
- Fix test annotations. Turns out Clang and GCC's 'undefined behavior'
  warning didn't align with the C++ standard.
