The old FIXME implies that we don't support escaped newlines, but in fact it
was added in the same patch that added support for escaped newlines.
The new FIXME makes it clear that we do currently support this, and that the
FIXME is for doing so in a less ad-hoc way.

Add `--no-capture`/`--nocapture` as bootstrap arguments
I often try `x test ... --nocapture` => 'unknown argument' => `x test ... -- --nocapture`. As we forward several other compiletest flags, let's recognise this one in bootstrap as well.

compiletest: Remove empty 'expected' files when blessing
Fixes #134793
Fixes #134196
This also refactors `compare_output` to return an enum; returning a usize was done for convenience but is misleading

Treat ; as a terminator rather part of a glued expression
|
|
|
|
This is a little more verbose, but also more explicit, and avoids invoking the
full condition engine when only the pointer-width conditions are used.

Migrate `incr-add-rust-src-component` to rmake
This PR partially supersedes #128562, and ports the Makefile-based `tests/run-make/incr-add-rust-src-component` to use rmake.rs infra.
Part of #121876.
This run-make test is a regression test for https://github.com/rust-lang/rust/issues/70924. It (tries to) checks that if we add the `rust-src` component in between two incremental compiles, that the compiler doesn't ICE on the second invocation.
- Original issue:https://github.com/rust-lang/rust/issues/70924
- Fix PR: https://github.com/rust-lang/rust/pull/72767
- PR adding this regression test: https://github.com/rust-lang/rust/pull/72952
However, the Makefile version of this used `$SYSROOT/lib/rustlib/src/rust/src/libstd/lib.rs`, but that actually got moved around and reorganized over the years. As of Dec 2024, the `rust-src` component is more like (specific for our purposes):
```
$SYSROOT/lib/rustlib/src/rust/
library/std/src/lib.rs
src/
```
However, this run-make test is ancient and it exercises incr-comp system logic. I'm not sure if this test would actually catch the original regression.

I'm fairly sure this is more correct, and saves space(~90mb to 82mb
for Zed's index). I'm checking in about this with SCIP folks in
https://github.com/sourcegraph/scip/pull/299.

Before this change `SymbolInformation` provided by a document was the
info for all encountered symbols that have not yet been emitted. So,
the symbol information on a `Document` was a mishmash of symbols
defined in the documents, symbols from other documents, and external
symbols.
After this change, the `SymbolInformation` on documents is just the
locals and defined symbols from the document. All symbols referenced
and not from emitted documents are included in `external_symbols`.

In particular, the symbol generation before this change creates a lot
of symbols with the same name for different definitions. This change
makes progress on symbol uniqueness, but does not fix a couple cases
where it was unclear to me how to fix (see TODOs in `scip.rs`)
Behavior changes:
* `scip` command now reports symbol information omitted due to symbol
collisions. Iterating with this on a large codebase (Zed!) resulted in
the other improvements in this change.
* Generally fixes providing the path to nested definitions in
symbols. Instead of having special cases for a couple limited cases of
nesting, implements `Definition::enclosing_definition` and uses this
to walk definitions.
* Parameter variables are now treated like locals.
- This fixes a bug where closure captures also received symbols
scoped to the containing function. To bring back parameter
symbols I would want a way to filter these out, since they can
cause symbol collisions.
- Having symbols for them seems to be intentional in
27e2eea54fbd1edeefa2b47ddd4f552a04b86582, but no particular use is
specified there. For the typical indexing purposes of SCIP I don't see
why parameter symbols are useful or sensible, as function parameters
are not referencable by anything but position. I can imagine they
might be useful in representing diagnostics or something.
* Inherent impls are now represented as `impl#[SelfType]` - a type
named `impl` which takes a single type parameter.
* Trait impls are now represented as `impl#[SelfType][TraitType]` - a
type named `impl` which takes two type parameters.
* Associated types in traits and impls are now treated like types
instead of type parameters, and so are now suffixed with `#` instead
of wrapped with `[]`. Treating them as type parameters seems to have
been intentional in 73d9c77f2aeed394cf131dce55807be2d3f54064 but it
doesn't make sense to me, so changing it.
* Static variables are now treated as terms instead of `Meta`, and so
receive `.` suffix instead of `:`.
* Attributes are now treated as `Meta` instead of `Macro`, and so
receive `:` suffix instead of `!`.
* `enclosing_symbol` is now provided for labels and generic params,
which are local symbols.
* Fixes a bug where presence of `'` causes a descriptor name to get
double wrapped in backticks, since both `fn new_descriptor` and
`scip::symbol::format_symbol` have logic for wrapping in
backticks. Solution is to simply delete the redundant logic.
* Deletes a couple tests in moniker.rs because the cases are
adequeately covered in scip.rs and the format for identifiers used in
moniker.rs is clunky with the new representation for trait impls
