20b1e05a8d Auto merge of #77502 - varkor:const-generics-suggest-enclosing-braces, r=petrochenkov 
Suggest that expressions that look like const generic arguments should be enclosed in brackets

I pulled out the changes for const expressions from https://github.com/rust-lang/rust/pull/71592 (without the trait object diagnostic changes) and made some small changes; the implementation is `@estebank's.`

We're also going to want to make some changes separately to account for trait objects (they result in poor diagnostics, as is evident from one of the test cases here), such as an adaption of https://github.com/rust-lang/rust/pull/72273.

Fixes https://github.com/rust-lang/rust/issues/70753.

Rollup merge of #78396 - josephlr:ermsb, r=petrochenkov 
Add compiler support for LLVM's x86_64 ERMSB feature

This change is needed for compiler-builtins to check for this feature
when implementing memcpy/memset. See:
  https://github.com/rust-lang/compiler-builtins/pull/365

Without this change, the following code compiles, but does nothing:
```rust
#[cfg(target_feature = "ermsb")]
pub unsafe fn ermsb_memcpy() { ... }
```

The change just does compile-time detection. I think that runtime
detection will have to come in a follow-up CL to std-detect.

Like all the CPU feature flags, this just references #44839

Rollup merge of #78394 - rubik:master, r=m-ou-se 
fix(docs): typo in BufWriter documentation

This PR fixes a small typo in the BufWriter documentation. The current documentation looks like this:

![2020-10-26-111501_438x83_scrot](https://user-images.githubusercontent.com/238549/97160357-83d3a000-177c-11eb-8a35-3cdd3a7d89de.png)

The `<u8>` at the end is mangled by Markdown. This PR makes the `BufWriter` documentation like the `BufReader` one:

https://github.com/rust-lang/rust/blob/master/library/std/src/io/buffered/bufreader.rs#L16

I'm tagging Steve as per the Rustc dev guide.

Rollup merge of #78342 - oliviacrain:checkmate-pass, r=Mark-Simulacrum 
Use check-pass in single-use-lifetime ui tests

Rationale: the `single_use_lifetimes` lint is used during late name resolution, which is within the scope of `check-pass` and does not require codegen or linking.

Helps remove some FIXMES associated with #62277. Additionally tidies touched test files.

Rollup merge of #76635 - scottmcm:slice-as-chunks, r=LukasKalbertodt 
Add [T]::as_chunks(_mut)

Allows getting the slices directly, rather than just through an iterator as in `array_chunks(_mut)`.  The constructors for those iterators are then written in terms of these methods, so the iterator constructors no longer have any `unsafe` of their own.

Unstable, of course. #74985
