rustc: Switch dsymutil status => output

Sometimes dsymutil writes to stdout/stderr which rust isn't reading, which may
cause a deadlock.

Closes #16060
making raw source display better

* Make the code fill up the full width of the page (no massive whitespace on the left)
* Move the code down to make it not intersect the logo
* Set a min-width and remove the max-width so that the code doesn't scroll internally, but instead scrolls the page, meaning horizontal scroll bars are always available
* Set overflow to actually overflow, just to be sure

Fixes #15891
doc: add missing word
Update LLVM to fix miscompilations due to wrongfully removed lifetime intrinsics

Fixes #15972 and #16011.
Elide lifetimes around Arc<T>.

It's a small step forward in application of RFC 39 to the code base
itself.

Gedit/gtksourceview language spec: add raw strings

… and color (raw) strings as such in attributes.
This fixes cases where a string contains ] inside an attribute:
that ] used to incorrectly end the attribute coloring.

For large (many lines) doc comments, I’ve found preferable to use
`#![doc = r#"..."#]` to avoid prefixing every line with `//!`.
Implement Hash for DList
syntax: add some more extension helper methods
syntax: allow quasiquoter to inline `Vec<Stmt>`s
syntax: promote a comment on PatEnum into a docstring
Fix a bug pretty printing `match { 5i } { _ => { } }`

This also always puts a trailing comma on the last non-block expr.
Use byte literals in std::ascii::ASCII_{UPPER,LOWER}_MAP for readability.
Make std::ascii::ASCII_{UPPER,LOWER}_MAP public.
Rename the std::ascii::{Owned,}StrAsciiExt traits to {Owned,}AsciiExt

… and implement them on Vec<u8> / &[u8].

[breaking-change]
Add deprecated aliases for the old {Owned,}StrAsciiExt trait names.

The deprecation warning does not seem to be emitted right now, but hopefully that’ll be fixed.
