Most tests involving save-analysis were removed, but I kept a few where
the `-Zsave-analysis` was an add-on to the main thing being tested,
rather than the main thing being tested.
For `x.py install`, the `rust-analysis` target has been removed.
For `x.py dist`, the `rust-analysis` target has been kept in a
degenerate form: it just produces a single file `reduced.json`
indicating that save-analysis has been removed. This is necessary for
rustup to keep working.
Closes#43606.
Enable new rlib in non stable cases
If bundled static library uses cfg (unstable) or whole-archive (wasn't supported) bundled libs are packed even without packed_bundled_libs.
r? `@petrochenkov`
This is somewhat important because LLVM enables the pass based on
target architecture, but support by the target OS also matters.
For example, XRay attributes are processed by codegen for macOS
targets, but Apple linker fails to process relocations in XRay
data sections, so the feature as a whole is not supported there
for the time being.

Move code in `rustc_driver` out to a new `rustc_driver_impl` crate to allow pipelining
That adds a `rustc_shared` library which contains all the rustc library crates in a single dylib. It takes over this role from `rustc_driver`. This is done so that `rustc_driver` can be compiled in parallel with other crates. `rustc_shared` is intentionally left empty so it only does linking.
An alternative could be to move the code currently in `rustc_driver` into a new crate to avoid changing the name of the distributed library.
Improve diagnostic for missing space in range pattern
Improves the diagnostic in #107425 by turning it into a note explaining the parsing issue.

Strengthen validation of FFI attributes
Previously, `codegen_attrs` validated the attributes `#[ffi_pure]`, `#[ffi_const]`, and `#[ffi_returns_twice]` to make sure that they were only used on foreign functions. However, this validation was insufficient in two ways:
1. `codegen_attrs` only sees items for which code must be generated, so it was unable to raise errors when the attribute was incorrectly applied to macros and the like.
2. the validation code only checked that the item with the attr was foreign, but not that it was a foreign function, allowing these attributes to be applied to foreign statics as well.
This PR moves the validation to `check_attr`, which sees all items. It additionally changes the validation to ensure that the attribute's target is `Target::ForeignFunction`, only allowing the attributes on foreign functions and not foreign statics. Because these attributes are unstable, there is no risk for backwards compatibility. The changes also ending up making the code much easier to read.
This PR is best reviewed commit by commit. Additionally, I was considering moving the tests to the `attribute` subdirectory, to get them out of the general UI directory. I could do that as part of this PR or a follow-up, as the reviewer prefers.

Skip possible where_clause_object_safety lints when checking `multiple_supertrait_upcastable`
Fix#106247
To achieve this, I lifted the `WhereClauseReferencesSelf` out from `object_safety_violations` and move it into `is_object_safe` (which is changed to a new query).

Detect references to non-existant messages in Fluent resources
Should help with cases like #107091, where `{variable}` (a message reference) is accidentally typed, rather than `{$variable}` (a variable reference)
Fixes#107370

Migrate mir_build's borrow conflicts
This also changes the error message slightly, for two reasons:
- I'm not a fan of saying "value borrowed, by `x`, here"
- it simplifies the error implementation significantly.
