write_verilog: correctly emit asynchronous transparent ports.
This commit fixes two related issues:
* For asynchronous ports, clock is no longer added to domain list.
(This would lead to absurd constructs like `always @(posedge 0)`.
* The logic to distinguish synchronous and asynchronous ports is
changed to correctly use or avoid clock in all cases.
Before this commit, the following RTLIL snippet (after memory_collect)
cell $memrd $2
parameter \MEMID "\\mem"
parameter \ABITS 2
parameter \WIDTH 4
parameter \CLK_ENABLE 0
parameter \CLK_POLARITY 1
parameter \TRANSPARENT 1
connect \CLK 1'0
connect \EN 1'1
connect \ADDR \mem_r_addr
connect \DATA \mem_r_data
end
would lead to invalid Verilog:
reg [1:0] _0_;
always @(posedge 1'h0) begin
_0_ <= mem_r_addr;
end
assign mem_r_data = mem[_0_];
Note that there are two potential pitfalls remaining after this
change:
* For asynchronous ports, the \EN input and \TRANSPARENT parameter
are silently ignored. (Per discussion in #760 this is the correct
behavior.)
* For synchronous transparent ports, the \EN input is ignored. This
matches the behavior of the $mem simulation cell. Again, see #760.

A typical use of `bugpoint` would involve a script with a pass under
test, e.g.:
flowmap -relax -optarea 100
and would be invoked as:
bugpoint -yosys ./yosys -script flowmap.ys -clean -cells
This replaces the current design with the minimal design that still
crashes the `flowmap.ys` script.
`bugpoint` can also be used to perform generic design minimization
using `select`, e.g. the following script:
select i:* %x t:$_MUX_ %i -assert-max 0
would remove all parts of the design except for an unbroken path from
an input to an output port that goes through exactly one $_MUX_ cell.
(The condition is inverted.)

opt_expr: improve simplification of comparisons with large constants.
The idea behind this simplification is that a N-bit signal X being
compared with an M-bit constant where M>N and the constant has Nth
or higher bit set, it either always succeeds or always fails.
However, the existing implementation only worked with one-hot signals
for some reason. It also printed incorrect messages.
This commit adjusts the simplification to have as much power as
possible, and fixes other bugs.
