Wire up cprng syscall as provider for rand::os::OsRng on Fuchsia.
This patch adds support for the aarch64-unknown-fuchsia target. Also updates src/liblibc submodule to include required libc change.
This avoids 800,000 heap allocations when compiling html5ever.
This avoids 800,000 heap allocations when compiling html5ever. It requires tweaking `SmallVector` a little.

Implement .fold() specifically for .map() and .cloned() so that any inner fold improvements are available through map and cloned.
Chain can do something interesting here where it passes on the fold into its inner iterators. The lets the underlying iterator's custom fold() be used, and skips the regular chain logic in next.
save_analysis: Dump data only if get_path_data doesn't fail to resolve a path. Solves rust-lang#37126 Dump data only if `get_path_data` doesn't fail to resolve a path. `get_path_data` returns `None` when it have to deals with `Def::Err`, which is used as placeholder for a failed resolution. Tell me if this is good enough, maybe I have to add some tests ? r? @nrc
Implement Iterator::fold for .chain(), .cloned(), .map() and the VecDeque iterators. Chain can do something interesting here where it passes on the fold into its inner iterators. The lets the underlying iterator's custom fold() be used, and skips the regular chain logic in next. Also implement .fold() specifically for .map() and .cloned() so that any inner fold improvements are available through map and cloned. The same way, a VecDeque iterator fold can be turned into two slice folds. These changes lend the power of the slice iterator's loop codegen to VecDeque, and to chains and flat maps of slice iterators, and so on. It's an improvement for .sum() and .product(), and other uses of fold.

Support `use *;` and `use ::*;`. Fixes rust-lang#31484. r? @nrc
Avoid more allocations when compiling html5ever These three commits reduce the number of allocations performed when compiling html5ever from 13.2M to 10.8M, which speeds up compilation by about 2%. r? @nrc
Prohibit patterns in trait methods without bodies
They are not properly type checked
```rust
trait Tr {
fn f(&a: u8); // <- This compiles
}
```
, mostly rejected by the parser already and generally don't make much sense.
This PR is kind of a missing part of rust-lang#35015.
Needs crater run.

…-ptr, r=eddyb rustc_typeck: Allow reification from fn item to unsafe ptr See rust-lang/rfcs#1762. I've never contributed to the compiler internals before-- apologies if I'm not going about this the right way.
Broken links in Vec docs Fixed some issues with quote/bracket nesting and made quoting more consistent. r? @steveklabnik
…chton Print out the error when HeapFree failures do occur cc rust-lang#37395 I'd prefer to use `assert!` instead of `debug_assert!` if the cost is acceptable. r? @alexcrichton
