After rust-lang/stdarch#825, these intrinsics are now defined with `#[rustc_args_required_const(2)]`, so the special-case is no longer necessary.
…ark-Simulacrum ci: switch macOS builders to 10.15 Azure Pipelines is deprecating the macOS 10.13 image we're currently running, [and they plan to remove them](https://devblogs.microsoft.com/devops/removing-older-images-in-azure-pipelines-hosted-pools/) on March 23, 2020. This PR switches our macOS builders to macOS 10.15. r? @Mark-Simulacrum
Add shared script for linkchecking books. This adds a script that can be used on each book's CI to ensure they don't break local links. I've been running something similar on the reference CI. The intent here is to add this to all the external books' CI scripts. This will help avoid dealing with broken links when updating submodules on rust-lang/rust.
Don't eliminate frame pointers on thumb targets This should hopefully fix issues rust-lang#69231 and rust-embedded/cortex-m-rt#139. ~~I couldn't test this locally as the rustc I produced does not create binaries (no idea why).~~ Resolved.
…pecial-case, r=petrochenkov Remove special case for `simd_shuffle` arg promotion After rust-lang/stdarch#825, these intrinsics are now defined with `#[rustc_args_required_const(2)]`, so the special-case is no longer necessary.

Reword OpenOptions::{create, create_new} doc.
Closes rust-lang#69254.
Currently, the doc comment for `fs::OpenOptions::create` doesn't mention its behaviour when opening an existing file, and `fs::OpenOptions::create_new`'s doc comment is worded in a way that doesn't make it clear that it actually _fails_ if the file already exists, not overwrite the existing file with a new one.
This PR addresses addresses this by rewording the doc comments to be more explicit.
