efa278e232 Fix typographical and grammatical errors and inconsistencies.
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.

ca866d384e write_verilog: handle the $shift cell.
The implementation corresponds to the following Verilog, which is
lifted straight from simlib.v:

    module \\$shift (A, B, Y);

    parameter A_SIGNED = 0;
    parameter B_SIGNED = 0;
    parameter A_WIDTH = 0;
    parameter B_WIDTH = 0;
    parameter Y_WIDTH = 0;

    input [A_WIDTH-1:0] A;
    input [B_WIDTH-1:0] B;
    output [Y_WIDTH-1:0] Y;

    generate
        if (B_SIGNED) begin:BLOCK1
            assign Y = $signed(B) < 0 ? A << -B : A >> B;
        end else begin:BLOCK2
            assign Y = A >> B;
        end
    endgenerate

    endmodule

Splitting VAR and ASSIGN into IVAR, VAR, DEFINE and ASSIGN. This allows better handling by nuXmv for post-processing (since now only state variables are listed under VAR).

93d19dc2fb Add support for module instances.
Don't pad logical operands to one bit.
Use operand width and signedness in $reduce_bool.
Shift amounts are unsigned and shouldn't be padded.
Group "is invalid" with the wire declaration, not its use (otherwise it is incorrectly wired to 0).

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)
