Don't duplicate last cdb debuginfo test command
cdb scripts interpret a blank line to mean "repeat the last command", similar to what happens when running the debugger from a console. The code for compiletest that constructs the debugger script was inserting a blank line between the last command and the "quit" command. This caused the last command to be executed twice. This can cause some confusion since the `-check` lines are expecting the output in a certain order. But printing the last command twice causes that order-assumption to fail, and that can cause confusion.
This fixes it by removing the blank line.
AFAICT, gdb and lldb scripts don't have the same behavior with blank lines (and the gdb code doesn't add any blank lines anyways).

Partial support for running UI tests with `download-rustc`
Right now trying to run UI tests with `download-rustc` results in a bunch of test failures, requiring someone who wants to only work on tests to also build the full compiler. This PR **partially** addresses the problem by solving a lot of the errors (but not all).
* This installs the `rust-src` component on CI toolchains, since the test output depends on whether the standard library source code is installed; We can't just symlink the current source because the `rustc-dev` component already includes the compiler sources, but not the library sources, and mixing things is worse IMO.
* This ensures the `$SRC_DIR` normalization done by compiletest correctly handles the source code added above.
* This unconditionally sets `remap-prefix` to the prefix used in the downloaded toolchain, to ensure compiletest normalizes it.

Add variant_name function to `LangItem`
Clippy has an internal lint that checks for the usage of hardcoded def paths and suggests to replace them with a lang or diagnostic item, if possible. This was implemented with a hack, by getting all the variants of the `LangItem` enum and then index into it with the position of the `LangItem` in the `items` list. This is no longer possible, because the `items` list can't be accessed anymore.
Follow up to #103603
cc `@camsteffen`
r? `@oli-obk`
This is blocking the sync between Clippy and Rust. I'm not sure if this is the best solution here, or if I should add a method `items()` to `LanguageItems` and keep the code in Clippy unchanged.
Fix `src/test/run-make/issue-36710` on cross-compiled targets
This PR fixes the `src/test/run-make/issue-36710` test not working on cross-compiled targets by telling the make infra how to run tests remotely with `remote-test-server`.
This PR includes a revert of #102723 (cc `@pcc),` which disabled that test on all cross-compiled targets.
Convert predicates into Predicate in the Obligation constructor
instead of having almost all callers do that.
This reduces a bit of boilerplate, and also paves the way for my work towards https://github.com/rust-lang/compiler-team/issues/531 (as it makes it easier to accept both goals and clauses where right now it only accepts predicates).

Record `LocalDefId` in HIR nodes instead of a side table
This is part of an attempt to remove the `HirId -> LocalDefId` table from HIR.
This attempt is a prerequisite to creation of `LocalDefId` after HIR lowering (https://github.com/rust-lang/rust/pull/96840), by controlling how `def_id` information is accessed.
This first part adds the information to HIR nodes themselves instead of a table.
The second part is https://github.com/rust-lang/rust/pull/103902
The third part will be to make `hir::Visitor::visit_fn` take a `LocalDefId` as last parameter.
The fourth part will be to completely remove the side table.
Use `token::Lit` in `ast::ExprKind::Lit`.
Instead of `ast::Lit`.
Literal lowering now happens at two different times. Expression literals are lowered when HIR is crated. Attribute literals are lowered during parsing.

cleanup and dedupe CTFE and Miri error reporting
It looks like most of the time, this error raised from const_prop_lint is just redundant -- it duplicates the error reported when evaluating the const-eval query. This lets us make `ConstEvalErr` private to the const_eval module which I think is a good step.
The Miri change mostly replaces a `match` by `if let`, and dedupes the "this error is impossible in Miri" checks.

This commit changes the language very slightly. Some programs that used
to not compile now will compile. This is because some invalid literals
that are removed by `cfg` or attribute macros will no longer trigger
errors. See this comment for more details:

Remove unused symbols and diagnostic items
As the title suggests, this removes unused symbols from `sym::` and `#[rustc_diagnostic_item]` annotations that weren't mentioned anywhere.
Originally I tried to use grep, to find symbols and item names that are never mentioned via `sym::name`, however this produced a lot of false positives (?), for example clippy matching on `Symbol::as_str` or macros "implicitly" adding `sym::`. I ended up fixing all these false positives (?) by hand, but tbh I'm not sure if it was worth it...
Fix x finding Python on Windows
`x` searches through the path for `{dir}/python{2|3}?`, but this fails on Windows because the appropriate path is `{dir}/python.exe`.
This PR adds the expected `.exe` extension on Windows while searching.
