Rollup merge of #61606 - petrochenkov:legclean, r=pnkfelix
Remove some legacy proc macro flavors
Namely
- `IdentTT` (`foo! ident { ... }`). Can be replaced with `foo! { ident ... }` or something similar.
- `MultiDecorator`. Can be replaced by `MultiModifier` (aka `LegacyAttr` after renaming).
- `DeclMacro`. It was a less powerful duplicate of `NormalTT` (aka `LegacyBang` after renaming) and can be replaced by it.
Stuff like this slows down any attempts to refactor the expansion infra, so it's desirable to retire it already.
I'm not sure whether a lang team decision is necessary, but would be nice to land this sooner because I have some further work in this area scheduled.
The documentation commit (https://github.com/rust-lang/rust/commit/a9397fd0d5eede4bbc0ada94bf92657ca8084cb3) describes how the remaining variants are different from each other and shows that there's actually some system behind them.
The last commit renames variants of `SyntaxExtension` in more systematic way.
- `ProcMacro` -> `Bang`
- `NormalTT` -> `LegacyBang`
- `AttrProcMacro` -> `Attr`
- `MultiModifier` -> `LegacyAttr`
- `ProcMacroDerive` -> `Derive`
- `BuiltinDerive` -> `LegacyDerive`
All the `Legacy*` variants are AST-based, as opposed to "modern" token-based variants.

Auto merge of #60793 - Xanewok:raw-string-cleanup, r=petrochenkov
lexer: Disallow bare CR in raw byte strings
Handles bare CR ~but doesn't translate `\r\n` to `\n` yet in raw strings yet~ and translates CRLF to LF in raw strings.
As a side-note I think it'd be good to change the `unescape_` to return plain iterators to reduce some boilerplate (e.g. `has_error` could benefit from collecting `Result<T>` and aborting early on errors) but will do that separately, unless I missed something here that prevents it.

typeck: Fix const generic in repeat param ICE.
This commit fixes an ICE that occured when a const generic was used in
a repeat expression. This was due to the code expecting the length of
the repeat expression to be const evaluatable to a constant, but a const
generic parameter is not (however, it can be made into a constant).

Rollup merge of #61683 - nielx:haiku-stack-limit, r=nagisa
Haiku: the maximum stack size is 16 MB
This keeps the compiler from crashing every time it is invoked. No functional change on other platforms.
This patch is similar to the limitation that is in the [librustdoc/lib.rs](https://github.com/rust-lang/rust/blob/57e13e0325c1d41161a31de1f8520538ec2c575c/src/librustdoc/lib.rs#L89).
Replaced linear token counting macros with optimized implementation
There are currently two distinct token-counting macros in the source. Both implement the trivial algorithm, with linear complexity. They may or may not be adequate for their use case, but considering that other people are probably going to copy and paste them whenever they need a token-counting macro, I replaced them with an optimized implementation with logarithmic complexity.
When one tries to create a thread with a requested stack size larger
than 16 MB, the call will fail and the compiler will bail out. Therefore
we should limit the size of the thread stack to 16 MB on Haiku.

Use Build::read_dir instead of fs::read_dir in Build::cp_r
Build::read_dir does better error handling when the directory doesn't
exist; it actually prints the name of the directory rather than just
printing the underlying error "No such file or directory" which on
its own isn't very useful.

Crater will be needed (done in https://github.com/rust-lang/rust/pull/60932#issuecomment-494188577, zero regressions) and then, if all goes well, FCP (in https://github.com/rust-lang/rust/pull/60932#issuecomment-494189802).

get rid of visit_place recursion

this is groundwork for https://github.com/rust-lang/rust/pull/60913, since after that PR we won't be able to implement `visit_place` in a recursive manner without heavy cloning everywhere.
