\| *	techmap/shift_shiftx: Remove the "shiftx2mux" special path.	Marcelina Kościelnicka	2020-08-20	3	-81/+38
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Our techmap rules for $shift and $shiftx cells contained a special path that aimed to decompose the shift LSB-first instead of MSB-first in select cases that come up in pmux lowering. This path was needlessly overcomplicated and contained bugs. Instead of doing that, just switch over the main path to iterate LSB-first (except for the specially-handled MSB for signed shifts and overflow handling). This also makes the code consistent with shl/shr/sshl/sshr cells, which are already decomposed LSB-first. Fixes #2346.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This reflects the behaviour of $shr/$shl, which sign-extend their A operands to the size of their output, then do a logical shift (shift in 0-bits).
