RawString error reporting cleanup
I simplified how errors with raw string are represented in the lexer and reportet in the parser, by using one enum instead of two structs with impls. This makes 70 code lines obsolete.
I also noticed some other things (2nd commit) and added a missing test for the `too many '#' symbols' error.
My original intent was to improve performance, but the only thing I found was to inline some functions in `cursor.rs`. It's effect is barely measurable, though.
There is one open question. Before, the compiler aborts when encountering the `too many '#' symbols` error. Now the lexer says in this case that there are 0 hashes, and then later the parser aborts on the error.
I'm worrying that the parser may be changed to recover and continue, and then later stages will see the wrong numer of hashes and act strange. (eg. the `format!` macro expansion).
Is that possibility important enough today to worry about it?
Make remote-test-client and remote-test-server compatible with windows
`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)

test miri-unleash TLS accesses
Finally gets rid of `IS_SUPPORTED_IN_MIRI`. :-)
I also added a test for the new `asm!` while I am at it.

rustc: Remove the `--passive-segments` LLD flag on wasm
This flag looks like it's been removed in LLVM 10, so this removes rustc
unconditionally passing the flag.
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:

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.
