The PR had some unforseen perf regressions that are not as easy to find.
Revert the PR for now.
This reverts commit 6ae8912a3e, reversing
changes made to 86d6d2b738.
Since RFC 3052 soft deprecated the authors field anyway, hiding it from
crates.io, docs.rs, and making Cargo not add it by default, and it is
not generally up to date/useful information, we should remove it from
crates in this repo.
Backports LLVM commit:
[APFloat] convert SNaN to QNaN in convert() and raise Invalid signal
149f5b573c
SNaN to QNaN conversion also matches what my Intel x86_64 hardware does.
