5548609204 Add const unstability attributes 
These are needed for rustc to be able to correctly handle stability of constness of intrinsics. Without either `rustc_const_unstable` or `rustc_const_stable` an intrinsic is not const evaluable at all.

c8249c76c4 Revert mmx changes 
On i586 the simd_* intrinsics don't compile to MMX instructions, even
with `#[target_feature(enable = "mmx")]`.

1772dc0ebf Don't use && on GitHub Actions. 
According to [*1], default shell of Windows is PowerShell. So `&&` isn't suppored on PowerShell yet.
So we should use multiline run syntax instead.

cca9a86637 Add CRC32 detection to arm32 
armv8 has 32-bit mode, but it can use crc32 instruction sets even if 32-bit.

7c56404f1a Add #[rustc_args_required_const] to simd_shuffle 
Currently, these have to be special-cased in the promotion logic for rustc.

9bb7286360 ci: switch mirrors to use our CDN 
We recently added a CDN in front of our CI mirrors as it's faster and
cheaper for us. This switches libc's CI to use it instead of accessing
the underlying bucket directly.

d7f3c0bbb3 Migrate CI to GitHub Actions (#813) 
* Migrate CI to GitHub Actions

This involves less secret and user management than azure pipelines, has
more concurrency by default for repos, and in general has a bit more
modern syntax!

* Disable clippy on CI for now

Looks like it's got quite a few errors
