fd302f46dc Store TokenStream in rmeta::MacroDef. 
This removes a hack from `load_macro_untracked` in which parsing is used.

80ed505c41 Use single-char patter on {ends,starts}_with and remove clone on copy type. 
These were introduced since I last fixed most of these occurences. (clippy::clone_on_copy, clippy::single_char_pattern)

d8d2004c6f Don't use "if let" bindings to only check a value and not actually bind anything. 
For example:  `if let Some(_) = foo() {}`	can be reduced to	`if foo().is_some() {}`   (clippy::redundant_pattern_matching)

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.

perf: Buffer stderr when writing json errors/warnings

Since `stderr` is unbuffered, writing out json messages actually take up
about ~10%/0.1s of the runtime of the `inflate` benchmark as it generates a fair number of warnings.

ee064befa0 Ensure diagnostics are printed in the correct order 
Even when buffered. Ideally we would flush only when the emitter is
done, but that requires larger changes. This gives most of the benefit
of buffering in any case.

Rollup merge of #66498 - bjorn3:less_feature_flags, r=Dylan-DPC 
Remove unused feature gates

I think many of the remaining unstable things can be easily be replaced with stable things. I have kept the `#![feature(nll)]` even though it is only necessary in `libstd`, to make regressions of it harder.

f8d830b4de Auto merge of #68376 - Centril:move-ref-patterns, r=matthewjasper 
Initial implementation of `#![feature(move_ref_pattern)]`

Following up on #45600, under the gate `#![feature(move_ref_pattern)]`, `(ref x, mut y)` is allowed subject to restrictions necessary for soundness. The match checking implementation and tests for `#![feature(bindings_after_at)]` is also adjusted as necessary.

Closes #45600.
Tracking issue: #68354.

Rollup merge of #68626 - Zoxc:termize, r=estebank 
Use termize instead of term_size

`termize` is a fork of `term_size` which uses `winapi` 0.3 instead of 0.2. This is a step towards removing the `winapi` 0.2 dependency.

Further improve `impl Trait`/`dyn Trait` suggestions

After reading [_Returning Trait Objects_ by Bryce Fisher-Fleig](https://bryce.fisher-fleig.org/blog/returning-trait-objects/), [I noticed that](https://www.reddit.com/r/rust/comments/esueur/returning_trait_objects/ffczl4k/) #68195 had a few bugs due to not ignoring `ty::Error`.

- Account for `ty::Error`.
- Account for `if`/`else` and `match` blocks when pointing at return types and referencing their types.
- Increase the multiline suggestion output from 6 lines to 20.

Rollup merge of #68256 - estebank:bad-sugg-span, r=petrochenkov 
Do not ICE on malformed suggestion spans

Under the assumption that suggestions are by their very nature always "best effort", it is ok if we don't display them instead of having an ICE. The underlying issue of the malformed span being _created_ is left unaddressed.

Fix #67567.
