dev-lang/rust: upgrade to 1.20

This upgrade is a fairly radical change from the previous version.
Features of the new ebuild and patches are:

- Rust version 1.20
- Uses the system LLVM
- Builds using clang
- Uses rustbuild instead of automake, which rustc dropped support for

The change from rustc's classic automake to the new rustbuild was the
bulk of the delay moving above 1.16. The change to using the system's
LLVM also added quite some challenge as both the system LLVM and rustc's
support for various LLVM versions were moving targets. Hopefully
upgrades to upstream Rust can be followed more closely now that these
hurdles hav been cleared.
