whitequark 00e7dec7f5 Replace "ILANG" with "RTLIL" everywhere.
The only difference between "RTLIL" and "ILANG" is that the latter is
the text representation of the former, as opposed to the in-memory
graph representation. This distinction serves no purpose but confuses
people: it is not obvious that the ILANG backend writes RTLIL graphs.

Passes `write_ilang` and `read_ilang` are provided as aliases to
`write_rtlil` and `read_rtlil` for compatibility.

Xiretza 916028906a Ensure \A_SIGNED is never used with $shiftx
It has no effect on the output ($shiftx doesn't perform any sign
extension whatsoever), so an attempt to use it should be caught early.

test_cell: don't generate directional shifts with \B_SIGNED=1
This was made an explicit error in e97e33d, "kernel: require \B_SIGNED=0
on $shl, $sshl, $shr, $sshr.".

Add flooring division operator
The $div and $mod cells use truncating division semantics (rounding
towards 0), as defined by e.g. Verilog. Another rounding mode, flooring
(rounding towards negative infinity), can be used in e.g. VHDL. The
new $divfloor cell provides this flooring division.

This commit also fixes the handling of $div in opt_expr, which was
previously optimized as if it was $divfloor.

Add flooring modulo operator
The $div and $mod cells use truncating division semantics (rounding
towards 0), as defined by e.g. Verilog. Another rounding mode, flooring
(rounding towards negative infinity), can be used in e.g. VHDL. The
new $modfloor cell provides this flooring modulo (also known as "remainder"
in several languages, but this name is ambiguous).

This commit also fixes the handling of $mod in opt_expr, which was
previously optimized as if it was $modfloor.

Henner Zeller 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)
