This should allow rustup and similar to actually make use of this new
target now.

This simplifies checking common properties in an address-family-agnostic
way since since rust-lang#86335 commits to not checking IPv4 semantics
of IPv4-mapped addresses in the `Ipv6Addr` property methods.

Reject all uses of the inline attribute on naked functions.

Properly find owner of closure in THIR unsafeck

Previously, when encountering a closure in a constant, the THIR unsafeck gets invoked on the owner of the constant instead of the constant itself, producing cycles.
Supersedes rust-lang#87492. ```@FabianWolff``` thanks for your work on that PR, I copied your test file and added you as a co-author.

Fixes rust-lang#87414.

Fix a parser ICE on invalid `fn` body

Fixes rust-lang#87635
A better fix would add a check for `fn` body on `expected_one_of_not_found` but I haven't come up with a graceful way. Any idea?

Followup to rust-lang#85782

Add convenience method for handling ipv4-mapped addresses by canonicalizing them

This simplifies checking common properties in an address-family-agnostic
way since rust-lang#86335 commits to not checking IPv4 semantics
of IPv4-mapped addresses in the `Ipv6Addr` property methods.

Correct typo

Allow generic SIMD array element type

Fixes the following:
```rust
#[repr(simd)]
struct V<T>([T; 4]);
```
