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

Respect \A_SIGNED for $shift
...
This reflects the behaviour of $shr/$shl, which sign-extend their A
operands to the size of their output, then do a logical shift (shift in
0-bits).

satgen: Move importCell out of the header.
...
This function has no hope of ever getting inlined anyway, and it speeds
up yosys compile time by 7%.
