Trevor Gross 2d857e1c21 Replace HasDomain to enable multi-argument edge case and domain tests 
This also allows reusing the same generator logic between logspace tests
and extensive tests, so comes with a nice bit of cleanup.

Changes:

* Make the generator part of `CheckCtx` since a `Generator` and
  `CheckCtx` are almost always passed together.
* Rename `domain_logspace` to `spaced` since this no longer only
  operates within a domain and we may want to handle integer spacing.
* Domain is now calculated at runtime rather than using traits, which is
  much easier to work with.
* With the above, domains for multidimensional functions are added.
* The extensive test generator code tests has been combined with the
  domain_logspace generator code. With this, the domain tests have just
  become a subset of extensive tests. These were renamed to "quickspace"
  since, technically, the extensive tests are also "domain" or "domain
  logspace" tests.
* Edge case generators now handle functions with multiple inputs.
* The test runners can be significantly cleaned up and deduplicated.

libm

A port of MUSL's libm to Rust.

Goals

The short term goal of this library is to enable math support (e.g. sin, atan2) for the wasm32-unknown-unknown target (cf. rust-lang/compiler-builtins). The longer term goal is to enable math support in the core crate.

Already usable

This crate is on crates.io and can be used today in stable #![no_std] programs.

The API documentation can be found here.

Benchmark

The benchmarks are located in crates/libm-bench and require a nightly Rust toolchain. To run all benchmarks:

cargo +nightly bench --all
