The `std::rt` module was marked `unstable` [a while back](b6d4d117f4), and this change was not reverted when we moved to an `experimental` baseline for `std`.
This is waiting on an RFC, but this basic functionality should be
straightforward. The implementation essentially desugars during type
collection and AST type conversion time into the parameter scheme we
have now.

The implementation essentially desugars during type collection and AST
type conversion time into the parameter scheme we have now. Only fully
qualified names--e.g. `<T as Foo>::Bar`--are supported.
RUST_LOG supports regex filtering of log messages with a syntax like
`RUST_LOG=main/foo` to use the regex filter 'foo'. Unfortunately, the
filter was inverted, so `RUST_LOG=main/foo` would actually show all
messages except the ones containing 'foo'.

Recursive items are currently detected in the `check_const` pass which runs after type checking. This means a recursive static item used as an array length will cause type checking to blow the stack. This PR separates the recursion check out into a separate pass which is run before type checking.
Closes issue #17252

Avoids warnings during bootstrap, similar to:
src/librustc/lib.rs:149:1: 149:39 warning: diagnostic code E0099 never used
src/librustc/lib.rs:149 __build_diagnostic_array!(DIAGNOSTICS)
All of these codes stopped being used in this commit:
688ddf7 ("typeck/kind -- stop using old trait framework.")
