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`).

symfpu: Add symfpu_convert
Convert one input to three outputs (int -> float, float -> int, float -> float).
No rounding mode, no flags (yet).

symfpu: Add -compare mode
Also `min` and `max` ops.  RISC-V uses IEEE 754-2019 semantics where `min(+0,-0) == -0` and `max(+0,-0) == +0` so we do the same here.  We could make it optional, but as I understand it the newer behavior is still backwards compatible (since previously it was valid to have selected either).

symfpu: Add alt2div
`altdiv` but without denormalization, because as it turns out HardFloat unpacks subnorms in the same way, so lets just support both styles.
