Re-implementation of zify
The logic is implemented in OCaml. By induction over the terms,
guided by registered Coq terms in ZifyInst.v, it generates a rewriting
lemma. The rewriting is only performed if there is some progress. If
the rewriting fails (due to dependencies), a novel hypothesis is
generated.
This PR fixes #5155, fixes #8898, fixes #7886, fixes #10707, fixes #9848
ans fixes #10755.
The zify plugin is placed in the micromega directory.
(Though the reason is unclear, having it in a separate directory is
bad for efficiency.) efficiency impact.
There are also a few improvements of lia/lra that are piggybacked.
- more aggressive pruning of useless hypotheses
- slightly optimised conjunctive normal form
- applies exfalso if conclusion is not in Prop
- removal of Timeout in test-suite
