Previously, we only displayed 'frame' numbers in a macro backtrace when more
than two frames were involved. This commit should help make backtrace
more readable, since these kinds of messages can quickly get confusing.
Eliminate confusing "globals" terminology.
There are some structures that are called "globals", but are they global
to a compilation session, and not truly global. I have always found this
highly confusing, so this commit renames them as "session globals" and
adds a comment explaining things.
Also, the commit fixes an unnecessary nesting of `set()` calls
`src/librustc_errors/json/tests.rs`

errors: use `-Z terminal-width` in JSON emitter
This PR makes the JSON emitter use `-Z terminal-width` in the "rendered" field of the JSON output.
r? @estebank
This commit modifies the column width computation in the emitter when
`termize::dimensions` returns `None` so that it uses the default value
of 140 (which is used in UI testing currently) instead of `usize::MAX`
which just ends up causing overflows in later computations. This is hard
to test but appears to produce the same output as using saturating
functions instead.

Handle assembler warnings properly
Previously all inline asm diagnostics were treated as errors, but LLVM sometimes emits warnings and notes as well.
Fixes#73160
r? @petrochenkov
Update annotate-snippets-rs to 0.8.0
#59346
I made major changes to this library. In the previous version we worked with owned while in the current one with borrowed.
I have adapted it without changing the behavior.
I have modified the coverage since the previous one did not return correctly the index of the character in the line.
They used to be covered by `optin_builtin_traits` but negative impls
are now applicable to all traits, not just auto traits.
This also adds docs in the unstable book for the current state of auto traits.
Revised span-to-lines conversion to produce an empty vec on DUMMY_SP.
This required revising some of the client code to stop relying on the returned set of lines being non-empty.
Fix#68808
more cleanups
* use starts_with() instead of chars().next() == Some(x)
* use subsec_micros() instead of subsec_nanos() / 1000
* use for (idx, item) in iter.enumerate() instead of manually counting loop iterations with variables
* use values() or keys() respectively when iterating only over keys or values of maps.
