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.

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.

symfpu: Configurable rounding modes
Including tests, but currently only testing rounding modes on multiply.
Also missing the ...01 case.

symfpu: Add flags
Use symfpu fork.
Add tests for symfpu properties and extra edge case checking for flags.
