rustc_std_internal_symbol is meant to call functions from crates where there is no direct dependency on said crate. As they either have to be added to symbols.o or rustc has to introduce an implicit dependency on them to avoid linker errors. The latter is done for some things like the panic runtime, but adding these symbols to symbols.o allows removing those implicit dependencies.
This used to be necessary for a correct linker order, but ever since the introduction of symbols.o adding the symbols in question to symbols.o would work just as well. We do still add dependencies on the panic runtime to the local crate, but not for #![needs_panic_runtime] crates. This also removes the runtime-depends-on-needs-runtime test. inject_dependency_if used to emit this error, but with symbols.o it is no longer important that there is no dependency and in fact it may be nice to have panic_abort and panic_unwind directly depend on libstd in the future for calling std::process::abort().
You shouldn't ever need to explicitly depend on it. And we weren't checking that the panic runtime used the correct panic strategy either.
There is already panic-unwind to enable it.

…nner, r=tgross35 Get rid of `EscapeDebugInner`. I read the note on `EscapeDebugInner` and thought I'd give it a try.
…sleywiser,ibraheemdev Reduce special casing for the panic runtime See the individual commits for more info.
…r=ChrisDenton Implement send_signal for unix child processes Tracking issue: rust-lang#141975 There are two main differences between my implementation and the Public API section of the tracking issue. ~First, `send_signal` requires a mutable reference, like `Child::kill`.~ Second, `ChildExt` has `Sealed` as a supertrait, bringing it more in line with other extension traits like `CommandExt`.
…s, r=jdonszelmann Refactor `rustc_attr_data_structures` documentation I was reading through `AttributeKind` and realized that attributes like `InlineAttr` didn't appear in it, however, I found them in `rustc_codegen_ssa` and understood why (guessing). There's almost no overall documentation for this crate, I've added the organized documentation at the top of `lib.rs`, and I've grouped the Attributes into two categories: `AttributeKind` that run all through the compiler, and the ones that are only used in `codegen_ssa`, such as `InlineAttr`, `OptimizeAttr`, `InstructionSetAttr`. Also, I've added documentation for `AttributeKind` that further explains why attributes like `InlineAttr` don't appear in it, with examples for each variant. r? `@jdonszelmann`
…enton Stabilize "file_lock" feature Closes rust-lang#130994 r? `@joshtriplett`
…v, r=RalfJung clarify `rustc_do_not_const_check` comment ~~Given that we have used this attribute for other reasons before it seems appropriate to make this a "usually".~~ Add function name as a pointer cc `@rust-lang/wg-const-eval`
…q, r=compiler-errors use `if let` guards where possible these crates already enable the feature
