819f1d8c20 Remove EXPLICIT_CARRY logic. 
The symbiflow-arch-defs tool chain no longer needs the EXPLICIT_CARRY
within yosys itself.

dc07ae9677 techmap: Add _TECHMAP_CELLNAME_ special parameter. 
This parameter will resolve to the name of the cell being mapped.  The
first user of this parameter will be synth_intel_alm's Quartus output,
which requires a unique (and preferably descriptive) name passed as
a cell parameter for the memory cells.

qbfsat, smt2, smtio: Add `-solver-option` to allow specifying SMT-LIBv2 `(set-option ...)` commands

smtio: Emit mode: start options before set-logic command and any other options after it. 
Refer to the SMT-LIB specification, section 4.1.7.  According to the spec, some options can only be specified in `start` mode.  Once the solver sees `set-logic`, it moves to `assert` mode.

85a1bb17ed 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%.

128522f173 verilog_backend: in non-SV mode, add a trigger for always @*. 
This commit only affects translation of RTLIL processes (for which
there is limited support).

Due to the event-driven nature of Verilog, processes like

    reg x;
    always @*
        x <= 1;

may never execute. This can be fixed in SystemVerilog code by using
`always_comb` instead of `always @*`, but in Verilog-2001 the options
are limited. This commit implements the following workaround:

    reg init = 0;
    reg x;
    always @* begin
        if (init) begin end
        x <= 1;
    end

Fixes #2271.
