| * | Add support for optimizing exists-forall problems.Alberto Gonzalez2020-03-133-1/+33
| | | | | | | | | | | | | | | | | | Modifies smt2 backend to recognize `$anyconst` etc. assigned to a wire with the `maximize` or `minimize` attribute and emit `; yosys-smt2-maximize` or `; yosys-smt2-minimize` directives as appropriate. Modifies `backends/smt2/smtbmc.py` and `smtio.py` to recognize those directives and emit a `(maximize ...)` or `(minimize ...)` command at the end of `smt_forall_assert()`, as described in the paper "νZ - An Optimizing SMT Solver" by Nikolaj Bjørner et al. Adds an example `examples/smtbmc/demo9.v` to show how it can be used.

This caused destruction of LUT5 initialization values. Since both nextpnr and yosys parser can also accept 32-bit parameters in the same encoding as other widths, let's just remove that special case. The old behavior is still left behind a `-compat-int` flag, in case someone relies on it.
