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 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.
