…able.comp Add TimeComputable.withMonotoneBound and PolyTimeComputable.withMonotoneBound, which replace a time bound with its partialSups (a monotone bound), and use them in PolyTimeComputable.comp so callers no longer need to supply a monotonicity proof. Add Polynomial.monotone_eval for canonically ordered semirings in Cslib/Foundations/Data/Polynomial/Monotone.lean. Supersedes leanprover#396.

To be honest, I'm not a big fan of pulling in all of polynomials just to define polynomial time, but this is a good increment, and we need the machinery in any case.

fixes #378.
This removes the
h_mono : Monotone hg.timeBoundassumption fromPolyTimeComputable.comp, by providing a way to convert a (poly)time-computable function into one with a monotone time bound.This PR supersedes #396, because that one seems abandoned, and it looks like this change is desired by some others.
