Stabilize the type_name intrinsic in core::any
Stabilize `type_name` in `core::any`.

Now that procedural macros no longer link transitively to libsyntax,
this shouldn't be needed any more! This commit is an experiment in
removing all dynamic libraries from rustc except for librustc_driver
itself. Let's see how far we can get with that!
The errors are either:
- The meta-variable used in the right-hand side is not bound (or defined) in the
left-hand side.
- The meta-variable used in the right-hand side does not repeat with the same
kleene operator as its binder in the left-hand side. Either it does not repeat
enough, or it uses a different operator somewhere.
This change should have no semantic impact.
Replaced linear token counting macros with optimized implementation
There are currently two distinct token-counting macros in the source. Both implement the trivial algorithm, with linear complexity. They may or may not be adequate for their use case, but considering that other people are probably going to copy and paste them whenever they need a token-counting macro, I replaced them with an optimized implementation with logarithmic complexity.
Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).
r? @steveklabnik
Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!
* Update bootstrap compiler
* Update version to 1.33.0
* Remove some `#[cfg(stage0)]` annotations
Actually updating the version number is blocked on updating Cargo
Currently, `BitSet` doesn't actually know its own domain size; it just
knows how many words it contains. To improve things, this commit makes
the following changes.
- It changes `BitSet` and `SparseBitSet` to store their own domain size,
and do more precise bounds and same-size checks with it. It also
changes the signature of `BitSet::to_string()` (and puts it within
`impl ToString`) now that the domain size need not be passed in from
outside.
- It uses `derive(RustcDecodable, RustcEncodable)` for `BitSet`. This
required adding code to handle `PhantomData` in `libserialize`.
- As a result, it removes the domain size from `HybridBitSet`, making a
lot of that code nicer.
- Both set_up_to() and clear_above() were overly general, working with
arbitrary sizes when they are only needed for the domain size. The
commit removes the former, degeneralizes the latter, and removes the
(overly general) tests.
- Changes `GrowableBitSet::grow()` to `ensure()`, fixing a bug where a
(1-based) domain size was confused with a (0-based) element index.
- Changes `BitMatrix` to store its row count, and do more precise bounds
checks with it.
- Changes `ty_params` in `select.rs` from a `BitSet` to a
`GrowableBitSet` because it repeatedly failed the new, more precise
bounds checks. (Changing the type was simpler than computing an
accurate domain size.)
- Various other minor improvements.
