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).

Add symfpu -classify 
Add description text for standard `symfpu` signature.

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.

symfpu: Add altsqrt 
No denormalization here.  That can be a problem for later (or not at all).

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.

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).

symfpu: Verifying rounding modes 
Works for everything but muladd.
Which I saw coming, but am still frustrated by.
