*	Add flooring division operator	Xiretza	2020-05-28	1	-0/+22
\| \| \| \| \| \| \| \| \| \|	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	Xiretza	2020-05-28	1	-0/+25
