mul2dsp: normalize operand order
...
Move the operand commute that puts the wider operand on A ahead of the
min-width checks. Checking the min-widths first made an asymmetric rule
(DSP_A_MINWIDTH != DSP_B_MINWIDTH) match only products that already had the
wider operand on A; a product in the other order was rejected before the
normalization.

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).

tests/symfpu: Extra muladd tests
...
Switch inputs back to `anyseq`, and add coverage for muladd with constant multiplier output and varying addend (also an assertion).
Use an `ifdef` to control clocked properties (because of the assertion, it's no longer just covers that are clocked).

tests/symfpu: Testing sqrt
...
Coverage supports `sqrt`, including new general rounding detection instead of just inf/ebmin/zero (since they aren't possible with `sqrt`).
More `sqrt` assertions, as well as the addition of `altsqrt` verification.
Some adjustments of macros.

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

tests/symfpu: Add cover checks

Include mask/map for abc inputs (and switch to `anyconst` instead of `anyseq`).
Add false divide check for mantissa.
Covers aren't currently being tested by anything (and have to be removed for `sat`), but I've been using it locally with SBY to confirm that the different edge cases are able to be verified (e.g. when verifying HardFloat against symfpu while using the masked inputs to reduce solver time).
