Compiler panics on armv7

[hessammehr]

On my ARM Samsung Chromebook 2 (crouton Ubuntu Xenial chroot):

cargo new --bin blank
cd blank
cargo run

   Compiling blank v0.1.0 (file:///home/hessammehr/Code/Rust/blank)
error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports

thread 'rustc' panicked at 'assertion failed: eps.windows(2).all(|w| w[0].cmp(self, &w[1]) != Ordering::Greater)', /buildslave/rust-buildbot/slave/nightly-dist-rustc-cross-host-linux/build/src/librustc/ty/context.rs:1525

(same thing happens if rustc is invoked directly, i.e. rustc src/main.rs.)

This is on a fresh nightly install with rustup:
