this UnknownBound variant is unfortunate and only here as a fallback for a couple Clean impls in case the DocContext isn't typed. I'm not quite sure why those impls call tcx_opt() and not tcx(). If it's safe to do so, I'd rather change those impls to use tcx() and get rid of this variant.

Anything which handles the tcx_opt() case is basically something called along the rustdoc --test path (if I recall correctly...). If you can bootstrap and run make check without having UnknownBound, feel free to remove it! You can also be lossy for things like this when tcx_opt() returns None because the only purpose is to crawl the documentation to learn about tests.

Rebased. Opted to just return a static region bound in those cases. |

…richton This PR adds support in rustdoc for properly naming lifetimes in bounds, instead of just showing `'static` for everything. It also adds support for unboxed function sugar bounds, which were also previously rendered as `'static`.
