Sort toolchains numerically

[dtolnay]

1.10.0 after 1.9.0 (or before, if we do reverse numeric order).

$ rustup toolchain list
stable-x86_64-unknown-linux-gnu
beta-x86_64-unknown-linux-gnu
nightly-x86_64-unknown-linux-gnu (default)
1.0.0-x86_64-unknown-linux-gnu
1.1.0-x86_64-unknown-linux-gnu
1.10.0-x86_64-unknown-linux-gnu
1.11.0-x86_64-unknown-linux-gnu
1.2.0-x86_64-unknown-linux-gnu
1.3.0-x86_64-unknown-linux-gnu
1.4.0-x86_64-unknown-linux-gnu
1.5.0-x86_64-unknown-linux-gnu
1.6.0-x86_64-unknown-linux-gnu
1.7.0-x86_64-unknown-linux-gnu
1.8.0-x86_64-unknown-linux-gnu
1.9.0-x86_64-unknown-linux-gnu

That sounds like a good idea to me! The sorting happens here. I think the right way to do this is by having a custom Ord impl for Component. Actually, the relevant function is toolchain_sort. Do you want to try implementing this? You can probably use https://crates.io/crates/natord.
