After adding tests, the current implementation for fminimum fails when
provided a negative zero and NaN as inputs:
---- math::fminimum_fmaximum_num::tests::fmaximum_num_spec_tests_f64 stdout ----
thread 'math::fminimum_fmaximum_num::tests::fmaximum_num_spec_tests_f64' panicked at libm/src/math/fminimum_fmaximum_num.rs:240:13:

Add more thorough spec tests for these functions and correct the
implementations.
Canonicalization is also moved to a trait method to centralize
documentation about what it does and doesn't do.
cleanup: Use `x.biteq(y)` rather than `x.to_bits() == y.to_bits()`2025-06-02T16:10:49+00:00Trevor Grosstmgross@umich.edu2025-06-02T16:10:49+00:00urn:sha1:e83ca863412a950f19fbc4e8fc632f19107dd0a2Replace `super::super` with `crate::support` where possible2025-05-05T06:31:52+00:00Trevor Grosstmgross@umich.edu2025-05-05T05:40:54+00:00urn:sha1:687902c1af4651ca0db9614c0a1ba6431cff266a
Since `crate::support` now works in both `compiler-builtins` and `libm`,
we can get rid of some of these unusual paths.
Refactor the fma modules2025-04-29T23:09:50+00:00Trevor Grosstmgross@umich.edu2025-04-29T20:52:54+00:00urn:sha1:caf337d46742aca1705c3254e8d45d7238a8435c
Move implementations to `generic/` like the other functions. This also
allows us to combine the `fma` and `fma_wide` modules.
Move `fma` implementations to `mod generic`2025-04-29T23:09:50+00:00Trevor Grosstmgross@umich.edu2025-04-29T20:50:58+00:00urn:sha1:6d83a3226f1401d777da0a91019caf2c3191b685
This will not build correctly, the move is done as a separate step from
the rest of refactoring so git's history is cleaner.

Apply the same formatting rules to both `libm` and `compiler-builtins`.
