Currently the Cargo binary has jumped from 14M to 34M on the beta channel, which
appears to be due to the fact that we're compiling tools with debug information
inside them. This additionally means that the `rls` binary is 62M right now!
This wasn't an intentional change, so be sure to disable debuginfo when
compiling tools as it's just intended for the standard library and compile for
now.
Part of #29368.
* Added a new summary paragraph about std::path's parsing facilities
* Slightly exanded `Component`'s docs
* removed the now redundant section on component types from the module docs
* moved the section on path normalization during parsing to the docs on
`Path::components`
* Clarified difference between `Prefix` and `PrefixComponent` in their
respecive summary sentences
Hoedown big comeback!

:vis matcher for macro_rules
Resurrection of @DanielKeep's implementation posted with [RFC 1575](https://github.com/rust-lang/rfcs/pull/1575).
@jseyfried was of the opinion that this doesn't need an RFC.
Needed before merge:
- [x] sign-off from @DanielKeep since I stole his code
- [x] feature gate
- [x] docs
Add a comment for disabling errexit, try to debug appveyor cache
Comments added as requested.
Also, lets add some cache debugging to appveyor. I *think* this is how to ignore errors in cmd.exe (and I did try it on my own machine), but I'm not 100% sure how appveyor runs them. In the worst case it'll fail but I guess that isn't the end of the world since the build has already failed by this point.

Specialize Vec::from_elem to use calloc
Fixes#38723. This specializes the implementation for `u8` only, but it could be extended to other zeroable types if desired.
I haven't tested this extensively, but I did verify that it gives the expected performance boost for large `vec![0; n]` allocations with both alloc_system and jemalloc, on Linux. (I have not tested or even built the Windows code.)
[rustbuild] Side-step HashMap iteration to preserve command-line step order.
The new `HashMap` was introduced by #41227 and it accidentally randomized step order.
r? @alexcrichton
Part of #29368.
* added missing links
* updated method summaries to use 3rd person style
* added missing periods in `Component`'s variant summaries
* use standard iterator boilerplate in `Components`' and `Iter`'s docs
* added example to `Iter::as_path`, adapted from `Components::as_path`'s
example
* consolidated examples for `Path::file_name`
* some other small fixes
rustc: provide adt_sized_constraint as an on-demand query.
By using `queries::adt_sized_constraint::try_get`, we can detect cycles without a separate stack.
