alumacc: cmp_mergeable function 
Replace all the existing mergeable checks with a call to a single function.
Fix remaining discrepencies (undersized output and mismatched signed inputs).

alumacc: Fix get_lt for oversized output 
Current behavior uses the output width to determine the MSb(s), however this is not correct if the output is larger than the inputs (which doesn't happen when creating an `$alu` for a compare op, but does when folding a compare op into an arithmetic `$alu`).

simplemap: Moves $pmux mapping from techmap.v to simple map 
This Fixes the slow downs I observed in techmap.v, which we
attempted to fix via the simplify ast.h route originally. This
turned out to be rather complex though.

By moving $pmux to simplemap we can just avoid that code. My
test case now runs in 310s which is 40s faster than the baseline
change.
