Don't demangle Rust symbols by default, but allow linking to rust-demangle.
The Rust compiler uses GCC C++ name mangling, but it has another layer of
encoding so abi::cxa_demangle doesn't produce great results. This patch
changes dump_syms to dump unmangled names by default so that consumers can
demangle them after-the-fact.
It also adds a tiny bit of support for linking against a Rust library I wrote
that can demangle Rust symbols nicely:
