Add wrap/unwrap return type in Option
I pretty much just copied over the code and tests for wrapping/unwrapping return types in `Result` and then did a bunch of find and replace changes.
I handled unwrapping statements returning `None` by just replacing `None` with the unit type, but I'm open to suggestions for more intuitive behavior here.
Add `set_last_error_and_return_i64`, change calls from
`this.libc_eval` to `LibcError`, and replace pairs of
`set_last_error` and returning values of the right type
with the new helper functions

Rip out old effects var handling code from traits
Traits no longer have an effect parameter, so this removes logic associated with it. It also removes logic surrounding confirming `~const Destruct` bounds, which I added a looooong time ago, and which I don't feel like we need anymore -- if it needs to be added back, it should be rewritten :D

Continue to get rid of `ty::Const::{try_}eval*`
This PR mostly does:
* Removes all of the `try_eval_*` and `eval_*` helpers from `ty::Const`, and replace their usages with `try_to_*`.
* Remove `ty::Const::eval`.
* Rename `ty::Const::normalize` to `ty::Const::normalize_internal`. This function is still used in the normalization code itself.
* Fix some weirdness around the `TransmuteFrom` goal.
I'm happy to split it out further; for example, I could probably land the first part which removes the helpers, or the changes to codegen which are more obvious than the changes to tools.

And few more fixups.
I was worried this will lead to more memory usage since `ExprOrPatId` is double the size of `ExprId`, but this does not regress `analysis-stats .`. If this turns out to be a problem, we can easily use the high bit to encode this information.
Instead of lowering them to `<expr> = <expr>`, then hacking on-demand to resolve them, we lower them to `<pat> = <expr>`, and use the pattern infrastructure to handle them. It turns out, destructuring assignments are surprisingly similar to pattern bindings, and so only minor modifications are needed.
This fixes few bugs that arose because of the non-uniform handling (for example, MIR lowering not handling slice and record patterns, and closure capture calculation not handling destructuring assignments at all), and furthermore, guarantees we won't have such bugs in the future, since the programmer will always have to explicitly handle `Expr::Assignment`.
Tests don't pass yet; that's because the generated patterns do not exist in the source map. The next commit will fix that.
Because our lint infra *can* handle allows from within macro expansions!
(Also, what did this reason have to do with something that is a hard error and not a lint? I'm puzzled).
I wonder how many such diagnostics we have...
Maybe that also mean we can change `unused_mut` to no-longer-experimental? But this is a change I'm afraid to do without checking.
compiletest: tidy up how `tidy` and `tidy` (html version) are disambiguated
Rename `has_tidy` -> `has_html_tidy` (`tidy` is also a bootstrap tool, but rustdoc uses a html tidy that has the same binary name). Follow-up to #131941.
Also apparently `runtest.rs` is short enough now, we can delete the `tidy` (bootstrap version) ignore for file length.
Register `src/tools/unicode-table-generator` as a runnable tool
It seems like `src/tools/unicode-table-generator` is not currently managed by bootstrap. This PR wires it up with bootstrap as a runnable tool.
This tool seems to take two possible args:
1. (Mandatory) path to `library/core/src/unicode/unicode_data.rs`, and
2. (Optional) path to generate a test file.
I only passed the mandatory path to `unicode_data.rs` in bootstrap and didn't do anything about (2). I'm not sure about how this tool is supposed to be run.
`Cargo.lock` is modified because I renamed `unicode-table-generator`'s bin name to match the tool name, as bootstrap's tool running logic expects the bin name to be derived from the tool name.
I also added a triagebot message to remind to not manually edit the library source file and edit the tool then regenerate instead, but this should probably be a tidy check (if that's desirable then that can be in a follow-up PR, though may be overkill).
Helps with #131640 but does not close it because still no docs.
r? `@Mark-Simulacrum` (since I think you authored this tool?)
Allow `#[deny]` inside `#[forbid]` as a no-op
Forbid cannot be overriden. When someome tries to do this anyways, it results in a hard error. That makes sense.
Except it doesn't, because macros. Macros may reasonably use `#[deny]` (or `#[warn]` for an allow-by-default lint) in their expansion to assert that their expanded code follows the lint. This is doesn't work when the output gets expanded into a `forbid()` context. This is pretty silly, since both the macros and the code agree on the lint!
By making it a warning instead, we remove the problem with the macro, which is now nothing as warnings are suppressed in macro expanded code, while still telling users that something is up.

compiler: Adopt rust-analyzer impls for `LayoutCalculatorError`
We're about to massively churn the internals of `rustc_abi`. To minimize the immediate and future impact on rust-analyzer, as a subtree that depends on this crate, grow some API on `LayoutCalculatorError` that reflects their uses of it. This way we can nest the type in theirs, and they can just call functions on it without having to inspect and flatten-out its innards.
compiletest: disambiguate html-tidy from rust tidy tool
when i first saw this error message i was very confused, i thought it was talking about `src/tools/tidy`. now it should be much more clear what tool should be installed.
Before this change, adding a lint was a difficult matter
because it always had some overhead involved. This was
because all lints would run, no matter their default level,
or if the user had #![allow]ed them. This PR changes that
internal: Fix editorconfig glob
Had been testing Zed's editorconfig branch on r-a and noticed that something was odd with yaml files.
https://spec.editorconfig.org/#glob-expressions
> {s1,s2,s3}
> any of the strings given (separated by commas, can be nested) (But {s1} only matches {s1} literally.)
