The compiler-rt library is fleshing out software support for this, so it would be nice if Rust exposed it as a type. It should be feature gated until the software implementation is complete since architectures with hardware support are still rare.

This currently requires linking against a library like libquadmath (or
libgcc), because compiler-rt barely has any support for this and most
hardware does not yet have 128-bit precision floating point. For this
reason, it's currently hidden behind a feature gate.

When compiler-rt is updated to trunk, some tests can be added for
constant evaluation since there will be support for the comparison
operators.

[`missing_panics_doc`] Fix rust-lang#13381

Fix rust-lang#13381

Makes `missing_panics_doc` act like other "panicking" lints (`unwrap_used`, `panic`, etc) in constant environments.
