This changes a lot of `.to_string()` to `.to_owned()`, removes a few redundant closures, and changes some `match`es to `if let`s.
I'm currently in the process of trying out clippy and acting on its suggestions. I started with compiletest, because we use it to test clippy, too. If this finds positive reception, I may continue refactoring other parts of the rust codebase.
This is a [breaking-change] for syntax extension authors. The fix is to use MultiModifier or MultiDecorator, which have the same functionality but are more flexible. Users of syntax extensions are unaffected.
I believe everything that doesn't take a constant integer up to SSE4.2
should now be correct (I don't have any reason to believe that those
that do take constant integers are wrong; they're just more complicated
and I just haven't tested them in detail).
(Also, takes out two unused code paths from trans.)

This adds a new Python script (compatible with 2.7 and 3.x) that will consume some JSON files that define a platform's intrinsics. It can output a file that defines the intrinsics in the compiler, or an `extern` block that will import them.
The complexity of the generator is to be DRY: platforms (especially ARM and AArch64) have a lot of repetition with their intrinsics, for different versions with different types, so being able to write it once is nice.
Do so by using the fact that fixed size arrays (like `[u8; 8]` can be coerced
to slices `&[u8]`, this is expressed through the trait `Unsize<[T]>` that all
fixed size arrays implement.
Still needs values of F_DUPFD_CLOEXEC on other OSs.
For Bitrig, NetBSD and OpenBSD the constant was incorrectly in posix01, when
it's actually posix08. In order to maintain backwards-compatiblity, the
constant was only copied, not moved.

Currently, `early_error` and `early_warn` in `librustc::session` always use `ColorConfig::Auto`. Modify them to follow the color configuration set by the `--color` option.
As colored output is also printed during the early stage, parsing the `--color` option should be done as early as possible. However, there are still some cases when the output needs to be colored before knowing the exact color settings. In these cases, it will be defaulted to `ColorConfig::Auto`, which is the same as before.
Fixes#27879.
