Point at the immutable local variable when trying to modify one of its
fields.
Given a file:
```rust
struct Foo {
pub v: Vec<String>
}
fn main() {
let f = Foo { v: Vec::new() };
f.v.push("cat".to_string());
}
```
present the following output:
```
error: cannot borrow immutable field `f.v` as mutable
--> file.rs:7:13
|
6 | let f = Foo { v: Vec::new() };
| - this should be `mut`
7 | f.v.push("cat".to_string());
| ^^^
error: aborting due to previous error
```
Change the wording of mutable borrow on immutable binding from "this should be `mut`" to "consider changing this to `mut f`".
…uct field reordering.
It does not seem valuable to always evaluate the right-hand side here.
Adds a test for issue rust-lang#31946 which was fixed a while ago.
Also update some 128 bit builtins to be panic-free without relying on the const evaluator.
Now it always implies right-alignment, so that padding zeroes are placed after the sign (if any) and before the digits. In other words, it always takes precedence over explicitly specified `[[fill]align]`. This also affects the '#' flag: zeroes are placed after the prefix (0b, 0o, 0x) and before the digits.

…orts, r=nrc Forbid conflicts between macros 1.0 exports and macros 2.0 exports This PR forbids for conflicts between `#[macro_export]`/`#[macro_reexport]` macro exports and `pub use` macro exports. For example, ```rust // crate A: pub use macros::foo; //^ This is allowed today, will be forbidden by this PR. // crate B: extern crate A; // This triggers a confusing error today. use A::foo; // This could refer to refer to either macro export in crate A. ``` r? @nrc
Implemente overflowing_sh* with new unchecked_sh* intrinsics Also update some 128 bit builtins to not rely on the constant evaluator to avoid checked operations. Fixes rust-lang#40508. cc @nagisa, @alexcrichton Note: I still have a build running to see if the 128 bit changes worked (unoptimized builds take *forever* to compile), however at least the overflowing builtins no longer reference `core::panicking::panic`.
add test for nested macro def (rust-lang#31946) Adds a test for issue rust-lang#31946 which was fixed in 1.12.0. Closes rust-lang#31946.
…r, r=nrc macros: improve the `TokenStream` quoter This PR - renames the `TokenStream` quoter from `qquote!` to `quote!`, - uses `$` instead of `unquote` (e.g. `let toks: TokenStream = ...; quote!([$toks])`), - allows unquoting `Token`s as well as `TokenTree`s and `TokenStream`s (fixes rust-lang#39746), and - to preserve syntactic space, requires that `$` be followed by - a single identifier to unquote, or - another `$` to produce a literal `$`. r? @nrc
Library stabilizations for 1.17 Details of the stabilizations are available in the commits. Includes only library stabilizations; there are a couple of compiler stabilizations that should also be done for 1.17. Will need a beta backport, which I will create after approval. r? @alexcrichton

minor wording tweak to slice::{as_ptr, as_mut_ptr}
Per rust-lang#37334, the slice-as-pointer methods mentioned that "modifying the slice may cause its buffer to be reallocated", when in fact modifying the *slice* itself would cause no such change. (It is a borrow, after all!) This is a tweak to the wording of that line to stress it's the *collection* that could cause the buffer to be reallocated.

Fix typo in mutex.rs docs This seems to match other uses of "be accessed" in the document.
…sfackler Fix a spelling error in HashMap documentation, and slightly reword surrounding text for precision Noticed while reading docs just now. It's possible that the prior wording *meant* to state that the seed's randomness depends on the exact instant that the system RNG was created, I guess. But unless there's an API guarantee that this is the case, the wording seems over-precise. Is there a formal API guarantee that would forbid, say, the system RNG from generating all output using the Intel RDRAND instruction? I don't think the quality of output in that case would depend on when the RNG was created. Yet it seems to me like it could well be a valid source of randomness when computing the initial seed. For that reason, tying the randomness of the seed, to the quality of the RNG's output *at the precise instant the seed is computed*, seems less confining. That instantaneous quality level could be determined by the quality at the instant the RNG was created -- but instantaneous quality need not be low for that precise reason.
