Update builders to rustc 1.14.0-beta.2 This beta release has a fix for the arm codegen issue with 1.13.0-stable, allowing us to use 1.13 language features everywhere. 1.14.0 will be in stable release before Firefox 53 goes to Aurora so the beta toolchain will only apply for part of the nightly phase.

Why?

To turn on --enable-rust support for Android quickly, thereby being able to default to --enable-rust?

And why exactly can't we do that with the version that's currently used, which is 1.12 on android and 1.13 elsewhere? And if we really want >= 1.13, why do we want to update across all platforms to work around 1.13's problems on arm, instead of only updating for android builds?

Using 1.14 beta would also fix bug 1311458, which is pretty important for crash reporting.

Sorry I failed to mention the debuginfo motivation. I think improving our crash reporting is worth the additional risk of building nightly with the beta toolchain.

Yeah, it'd be great to land this, if possible. There are a bunch of bugs around crash reporting that are waiting on this to see if it changes the experience: https://bugzilla.mozilla.org/showdependencytree.cgi?id=1268328&hide_resolved=1

Mac builds failed on try because the cargo binary dynamically links homebrew's openssl in /usr/local/opt/openssl which the builders don't have. I filed https://github.com/rust-lang/cargo/issues/3320 to address that. In the meantime I'll remove the Mac bump from the patch in the interest of landing this for the other platforms.
