Rephrase term 'non-pointer type'
Hello 🐈 ,
If the reader assumes that 'pointer type's include 'smart pointer's,
the term 'non-pointer type' could mislead the reader to assume that
x should not be a smart pointer type. I tried to rephrase the term
'non-pointer type' to remove ambiguity in the doc comments.

Add descriptions for all queries
This also removes the default description for queries with DefId keys and makes the macro validate that a description is provided.

fulfill: try using SmallVec or Box for stalled_on
Tested both `Box` and `SmallVec` for `stalled_on`, with both resulting in a perf loss.
Adds a comment mentioning this and removes an now outdated FIXME.
Logging the length of `stalled_on` resulted in the following distribution while building a part of stage 1 libs:

Normally, we debug-print `Spans` using the `SourceMap` retrieved from
the global `TyCtxt`. However, we fall back to printing out the `Span`'s
raw fields (instead of a file and line number) when we try to print a
`Span` before a `TyCtxt` is available. This makes debugging early phases
of the compile, such as parsing, much more difficult.
This commit stores a `SourceMap` in `rustc_span::GlOBALS` as a fallback.
When a `TyCtxt` is not available, we try to retrieve one from `GLOBALS`
- only if this is not available do we fall back to the raw field output.
I'm not sure how to write a test for this - however, this can be
verified locally by setting `RUSTC_LOG="rustc_parse=debug"`, and
verifying that the output contains filenames and line numbers.

the term 'non-pointer type' could mislead the reader to assume that

Clarify terms in doc comments
Doc comments of `copy_from_slice` say that people should use `clone_from_slice`
when 'src' doesn't implement `Copy`. However, 'src' is a reference and
it always implements `Copy`. The term 'src' should be fixed to `T`(element type of slice 'src') in
the doc comments.

Miri tests: skip parts of test_char_range
The new `test_char_range` test takes forever in Miri as it loops over all values of `char`. This makes it skip most of them when being run in Miri.
Avoid setting wrong obligation cause span of associated type mismatch
Removes code that sets wrong obligation cause span of associated type mismatch. See the linked issue for details.
Closes#72806.
Fix escape key handling
Fixes#72647.
The problem was that you could have a timeout just after the moment you press "escape", putting back the results.

Track devirtualized filenames
Split payload of FileName::Real to track both real and virtualized paths.
(Such splits arise from metadata refs into libstd; the virtualized paths look like `/rustc/1.45.0/src/libstd/io/cursor.rs` rather than `/Users/felixklock/Dev/Mozilla/rust.git/src/libstd/io/cursor.rs`)
This way, we can emit the virtual name into things like the like the StableSourceFileId (as was done back before PR #70642) that ends up in incremental build artifacts, while still using the devirtualized file path when we want to access the file.
Fix#70924
`compiletest` and `remote-test-client`:
The command line for `remote-test-client` was changed slightly
to allow cross-platform compatible paths. The old way of supplying
the support libs was by joining their paths with the executable path
with `:`. This caused Windows-style paths to be split after the
directory letter. Now, the number of support libs is provided
as a parameter as well, and the support lib paths are split off
from the regular args in the client.
`remote-test-server`:
- Marked Unix-only parts as such and implemented Windows alternatives
- On Windows `LD_LIBRARY_PATH` doesn't exist. Libraries are
loaded from `PATH` though, so that's the way around it.
- Tiny cleanup: `Command::args`/`envs` instead of manually
looping over them
- The temp path for Windows has to be set via environment variable,
since there isn't a global temp directory that would work on every
machine (as a static string)
