Put off array bound evaluation / describe entity generics as parameters
...
Entity generics are easily implemented as module parameters, so make
it so. Give the parameters their default values from the generic declaration.
Array bounds may use values that cannot be evaluated right away, so
put off their evaluation.

Fix long division.
...
On a 64-bit machine the following module shows incorrect division
results:
`define X {4'b 1000, `N'b 0}
`define Y {1'b 1, `N'b 0}
module b;
reg [`N:0] y = `Y;
reg [3:0] z1, z2;
initial begin
z1 = `X / `Y;
z2 = `X / y;
$display("%3d %b %b", `N, z1, z2);
end
endmodule // b
$ for N in {60..65}; do /usr/bin/iverilog -DN=$N -oa b.v && /usr/bin/vvp a; done

code generators.
It fixes the parser to correctly have the range after the signed
designation for the vector types.
It adds a warning that vvp does not currently support a negative
two state enumeration value.

Fix for pr3397689.
...
This is caused by a bug in some simple pattern matching the VHDL target does to try
and produce more idiomatic code in common cases (e.g. FFs with asynchronous resets in
this case). This patch just restricts the kinds of if-statements we use this
optimisation for.
