Bit-magic for faster is_char_boundary
The asm generated for b < 128 || b >= 192 is not ideal, as it computes
both sub-inequalities. This patch replaces it with bit magic.
Fixes#32471
Adds data race in docs
Thanks for all your hard work!
This is in reference to #32733
I know there has been a discussion about this on PR #32538 so you are welcome to keep the code as is or merge my documentation in.
Let me know what you think and/or if you want me to modify anything!
* Copy documentation from signed implementation to unsigned implementation, where necessary.
* Use signed integers in signed documentation, where possible.
Set the version number for stabilization of braced_empty_structs
and augmented_assignment to 1.8.0.
Per the comments, the numbers in this table reflect the "current
status".

Discovered this while hunting for 1.8 features. I'm afraid there may be more of these that are incorrect and we may have created a mess.
Blacklist fn item types from being used with variadic functions.
Fixes#32201 by adding fn types to the variadic blacklist which currently includes `bool`, `i8`, `u8`, `i16`, `u16` and `f32`.
The path `/etc/rustc/` is not the default last entry in
RUST_TARGET_PATH. This was in RFC131 but was never implemented in rustc
so it was removed as part of #31117 and rust-lang/rfcs#1473.

Extract the code that performs the initialization of the LLVM backend
and invoke it before computing the available features. The
initialization is required to happen before the features are added to
the configuration, because they are computed by LLVM, therefore is is
now performed when creating the `Session` object.
rustbuild: Support cross rust-docs packages
Right now if you configure multiple hosts rustbuild will only build
documentation for the build triple, but we've got all the support necessary to
build documentation for different architectures as well. This commit
reinterprets the `target` field of doc `Step` instances to be the target of the
documentation rather than the target of the rustdoc/tool being run.
This should enable `make dist` to start producing a bunch of `rust-docs`
packages for all the cross architectures that rustbuild is producing now.
Release notes for 1.8
cc @steveklabnik to me the highlights are compound assignment overloading, 32-bit MSVC builds being ready for use, and the cargo improvements.

Handle operand temps for function calls
Previously, all non-void function returns required an on-stack location for the value to be stored to. This code improves translation of function calls so this is no longer necessary.
