Add explanations for E0503 and E0508.
(cannot use `..` because it was mutably borrowed, cannot move out of type `..`, a non-copy fixed-size array)
Part of #32777.
add a test case for issue #32031
I propose a test case to finish the fix for issue #32031. Please review this commit thoroughly, as I have never written a codegen test before.

rustdoc: Don't generate empty files for stripped items
We need to traverse stripped modules to generate redirect pages, but we shouldn't generate
anything else for them.
This now renders the file contents to a Vec before writing it to a file in one go. I think
that's probably a better strategy anyway.
Fixes: #34025
Remove linking and intrinsics code made dead by only supporting LLVM 3.7 and up
This is mostly based on Alex's throwaway comment:
> probably reject those that LLVM just doesn't support...
So I'm more than happy to adjust the PR based on how you thought this should look. Also happy to split it into two PRs, one for linking and one for intrinsics.

Treat `#[test]` like `#[cfg(test)]` in non-test builds
This PR treats `#[test]` like `#[cfg(test)]` in non-test builds. In particular, like `#[cfg(test)]`,
- `#[test]` nodes are stripped during `cfg` processing, and
- `#[test]` is disallowed on non-optional expressions.
Closes#33946.

Visit statement and expression attributes in the AST visitor
Currently, these attributes are not visited, so they are not gated feature checked in the post expansion visitor. This only affects crates using `#![feature(stmt_expr_attributes)]`.

docs: Improve char::to_{lower,upper}case examples
Collect the results to a String to make it clear that it will not always
return only one char and add examples showing that.

Updated README to account for changes in MSYS2
One of the newest versions of MSYS2 now only has one .cmd file which replaces the old bat files. It has to be used to launch the mingw32/64 shell.
docs: simplify wording
It took me more then a moment to decipher "with no non-`'static`" thing :)
"`'static` type" should say the same thing more clearly.

Remove a gotcha from book/error-handling.md
The book's "Error handling with `Box<Error>`" section talks about `Box<Error>`. In the actual example `Box<Error + Send + Sync>` is used instead so that the corresponding From impls could be used to convert a plain string to an error type. Rust 1.7 added support for conversion from `&str`/`String` to
`Box<Error>`, so this gotcha and later references to it can now be removed.

Reflect supporting only LLVM 3.7+ in the LLVM wrappers
Based on 12abddb06b, it appears we can drop support for these older LLVM versions. Hopefully, this will make it slightly easier to support the changes needed for LLVM 3.9.
