Marcelina Kościelnicka 63b9df8693 kernel/ff: Refactor FfData to enable FFs with async load.
- *_en is split into *_ce (clock enable) and *_aload (async load aka
  latch gate enable), so both can be present at once
- has_d is removed
- has_gclk is added (to have a clear marker for $ff)
- d_is_const and val_d leftovers are removed
- async2sync, clk2fflogic, opt_dff are updated to operate correctly on
  FFs with async load

Marcelina Kościelnicka 03e28f7ab4 clk2fflogic: Consistently treat async control signals as negative hold.
This fixes some dfflegalize equivalence checks, and breaks others — and
I strongly suspect the others are due to bad support for multiple
async inputs in `proc` (in particular, lack of proper support for
dlatchsr and sketchy circuits on dffsr control inputs).

Alberto Gonzalez 903456c267
qbfsat: Add `-solver` option and allow choice of Z3 or Yices, making Yices the default.
Ensures that "BV" is the logic whenever solving an exists-forall problem with Yices, moves the "(set-logic ...)" directive above any non-info line, sets the `ef-max-iters` parameter to a very high number when using Yices in exists-forall mode so as not to prematurely abandon difficult problems, and does not provide the incompatible "--incremental" Yices argument when in exists-forall mode.

whitequark b43c282e4e Add WASI platform support.
This includes the following significant changes:
  * Patching ezsat and minisat to disable resource limiting code
    on WASM/WASI, since the POSIX functions they use are unavailable.
  * Adding a new definition, YOSYS_DISABLE_SPAWN, present if platform
    does not support spawning subprocesses (i.e. Emscripten or WASI).
    This definition hides the definition of `run_command()`.
  * Adding a new Makefile flag, DISABLE_SPAWN, present in the same
    condition. This flag disables all passes that require spawning
    subprocesses for their function.

Ben Widawsky 8767ec3fbd Add a few more filename rewrites
This now allows a full pipeline to work, something such as:
yosys -p "synth_ecp5 -json ~/work/fpga/prjtrellis/examples/ecp5_evn/blinky.v"

Otherwise, you will get something along the lines of:
ERROR: Can't open output file `~/work/fpga/prjtrellis/examples/ecp5_evn/blinky.v' for writing: No such file or directory

Henner Zeller 3aa4484a3c Consistent use of 'override' for virtual methods in derived classes.
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)
