Release rayon 1.0.1

[cuviper]

We've made a few improvements to documentation, but these need to be published
to reach docs.rs. Fixes #555.

error: Could not compile `rayon`.

I'll gather more info and file it upstream, then probably just add the type annotation here.

I filed rust-lang/rust#49062.

For some reason, updating compiletest_rs from 0.3.7 to 0.3.8 broke sum() inference in a lot of totally unrelated tests. I wrote commit dcf720b with the type annotations as a workaround, although I accidentally pushed it directly to master, sorry! We'll see if CI likes it here now...
