Miri function identity hack: account for possible inlining Having a non-lifetime generic is not the only reason a function can be duplicated. Another possibility is that the function may be eligible for cross-crate inlining. So also take into account the inlining attribute in this Miri hack for function pointer identity. That said, `cross_crate_inlinable` will still sometimes return true even for `inline(never)` functions: - when they are `DefKind::Ctor(..) | DefKind::Closure` -- I assume those cannot be `InlineAttr::Never` anyway? - when `cross_crate_inline_threshold == InliningThreshold::Always` so maybe this is still not quite the right criterion to use for function pointer identity.
From LLVM 15.0.0-rc3. This adds support for COFF archives containing Arm64EC object files and has various fixes for AIX big archive files.

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
The `weak-intrinsics` feature was removed from compiler_builtins in rust-lang/compiler-builtins#598, so dropped the `compiler-builtins-weak-intrinsics` feature from alloc/std/sysroot. In rust-lang/compiler-builtins#593, some builtins for f16/f128 were added. These don't work for all compiler backends, so add a `compiler-builtins-no-f16-f128` feature and disable it for cranelift and gcc. Also disable it for LLVM targets that don't support it.
