On nightly, dump ICE backtraces to disk

Implement rust-lang/compiler-team#578.

When an ICE is encountered on nightly releases, the new rustc panic handler will also write the contents of the backtrace to disk. If any `delay_span_bug`s are encountered, their backtrace is also added to the file. The platform and rustc version will also be collected.

The current behavior will *always* write to disk on nightly builds, regardless of whether the backtrace is printed to the terminal, unless the environment variable `RUSTC_ICE_DISK_DUMP` is set to `0`. This is a compromise and can be changed.
