I rarely need a debug build of cg_clif, and even if I actually need one,
using package overrides in Cargo.toml to only do a debug build for the
rustc_codegen_cranelift crate works much better.
This has found a couple of new abi issues. I also had to disable the
abi-cafe tests for the MinGW target as one of these abi issues causes a
hang and abi-cafe doesn't yet support timeouts.
Update compiler_builtins to 0.1.114
The `weak-intrinsics` feature was removed from compiler_builtins in https://github.com/rust-lang/compiler-builtins/pull/598, so dropped the `compiler-builtins-weak-intrinsics` feature from alloc/std/sysroot.
In https://github.com/rust-lang/compiler-builtins/pull/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.

As decided in rust-lang/compiler-team#750.
Use declarations are currently wildly inconsistent because rustfmt is
quite unopinionated about how they should be formatted. The
`rustfmt.toml` additions makes rustfmt more opinionated, which avoids
the need for any decision when adding new use declarations to a file.
This commit only updates `rustfmt.toml` and
`compiler/rustc_codegen_cranelift/rustfmt.toml`. The next commit will do
the reformatting.
It is a worse option than using `CARGO_PROFILE_DEV_CODEGEN_BACKEND`.
When using `--target` it doesn't apply to build scripts and proc macros.
It also overrides any `RUSTFLAGS` you may have set in an env var or
cargo config.
Add a hook for `should_codegen_locally`
This PR lifts the module-local function `should_codegen_locally` to `TyCtxt` as a hook.
In addition to monomorphization, this function is used for checking the dependency of `compiler_builtins` on other libraries. Moving this function to the hooks also makes overriding it possible for the tools that use the rustc interface.
