- Change llvm_bundling to be required on s390x on 15.3 due to an llvm11
codegen issue.

Version 1.54.0 (2021-07-29)
Language
- [You can now use macros for values in built-in attribute macros.][83366]
While a seemingly minor addition on its own, this enables a lot of
powerful functionality when combined correctly. Most notably you can
now include external documentation in your crate by writing the following.
```rust
[#]![doc = include_str!("README.md")]
```
You can also use this to include auto-generated modules:
```rust
[#][path = concat!(env!("OUT_DIR"), "/generated.rs")]
mod generated;
```
- [You can now cast between unsized slice types (and types which contain
unsized slices) in `const fn`.][85078]
- [You can now use multiple generic lifetimes with `impl Trait` where the
lifetimes don't explicitly outlive another.][84701] In code this means
that you can now have `impl Trait<'a, 'b>` where as before you could
only have `impl Trait<'a, 'b> where 'b: 'a`.
Compiler
- [Rustc will now search for custom JSON targets in
`/lib/rustlib/<target-triple>/target.json` where `/` is the "sysroot"
directory.][83800] You can find your sysroot directory by running
`rustc --print sysroot`.
- [Added `wasm` as a `target_family` for WebAssembly platforms.][84072]
- [You can now use `#[target_feature]` on safe functions when targeting
WebAssembly platforms.][84988]
- [Improved debugger output for enums on Windows MSVC platforms.][85292]
- [Added tier 3\* support for `bpfel-unknown-none`
and `bpfeb-unknown-none`.][79608]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
- [`panic::panic_any` will now `#[track_caller]`.][85745]
- [Added `OutOfMemory` as a variant of `io::ErrorKind`.][84744]
- [ `proc_macro::Literal` now implements `FromStr`.][84717]
- [The implementations of vendor intrinsics in core::arch have been
significantly refactored.][83278] The main user-visible changes are
a 50% reduction in the size of libcore.rlib and stricter validation
of constant operands passed to intrinsics. The latter is technically
a breaking change, but allows Rust to more closely match the C vendor
intrinsics API.
Stabilized APIs
- [`BTreeMap::into_keys`]
- [`BTreeMap::into_values`]
- [`HashMap::into_keys`]
- [`HashMap::into_values`]
- [`arch::wasm32`]
- [`VecDeque::binary_search`]
- [`VecDeque::binary_search_by`]
- [`VecDeque::binary_search_by_key`]
- [`VecDeque::partition_point`]
Cargo
-----
- [Added the `--prune <spec>` option to `cargo-tree` to remove a package from
the dependency graph.][cargo/9520]
- [Added the `--depth` option to `cargo-tree` to print only to a certain depth
in the tree ][cargo/9499]
- [Added the `no-proc-macro` value to `cargo-tree --edges` to hide procedural
macro dependencies.][cargo/9488]
- [A new environment variable named `CARGO_TARGET_TMPDIR` is available.][cargo/9375]
This variable points to a directory that integration tests and benches
can use as a "scratchpad" for testing filesystem operations.
