This commit adds a test that demonstrates the compiler's current
behaviour when a function attempts to return a value that was unwrapped
by a `?` operator when the omission of `?` would have made the code
compile.
This commit adds a test demonstrating the current behaviour when a macro
defined in a module with the `#[macro_export]` is imported from the
module rather than the crate root.
Revert "Auto merge of #57842 - gnzlbg:extract_libtest, r=gnzlbg"
This reverts commit 3eb4890dfe, reversing
changes made to 7a4df3b53d.
This is, as best I can tell, a clean revert of #57842. It retains some interim changes, like moving `black_box`, and otherwise brings libtest back in as it was before removal.
ci: pin android emulator to 28.0.23
Apparently Android Emulator 28.0.25 (the latest one) is broken for us, and `sdkmanager` doesn't have a way to pin a package to a specific version. This PR stops downloading the emulator from `sdkmanager`, downloading it manually instead.
Tested this locally and confirmed it works. I'll open an issue on Google's issue tracker later today.

Use for_each to extend collections
This updates the `Extend` implementations to use `for_each` for many
collections: `BinaryHeap`, `BTreeMap`, `BTreeSet`, `LinkedList`, `Path`,
`TokenStream`, `VecDeque`, and `Wtf8Buf`.
Folding with `for_each` enables better performance than a `for`-loop for
some iterators, especially if they can just forward to internal
iterators, like `Chain` and `FlatMap` do.
rustc: Start implementing compat with LLVM 9
This commit doesn't actually migrate to LLVM 9, but it brings our own
C++ bindings in line with LLVM 9 and able to compile against tip of
tree. The changes made were:
* The `MainSubprogram` flag for debuginfo moved between flag types.
* Iteration of archive members was tweaked slightly and we have to
construct the two iterators before constructing the returned
`RustArchiveIterator` value.
* The `getOrInsertFunction` binding now returns a wrapper which we use
`getCallee()` on to get the value we're interested in.
Change `copytest` parameter name from `y` to `sign`
This should help clarify ambiguity with whether `a.copysign(b)` applies the sign of `a` to `b` or `b` to `a`.

Show better errors for LLVM IR output
I was trying to output LLVM IR directly to the console:
$ rustc hello.rs --emit=llvm-ir -o /dev/stdout
LLVM ERROR: IO failure on output stream: Bad file descriptor
Now `LLVMRustPrintModule` returns an error, and we print:
error: failed to write LLVM IR to /dev/stdout.hello.7rcbfp3g-cgu.0.rcgu.ll: Permission denied
... which is more informative.

wasi: Use shared API for preopened fds
This commit updates the wasi target with supported added in
CraneStation/wasi-sysroot#10. That function allows both C and Rust to
cooperate in how preopened files are managed, enabling us to learn about
propened files through the same interface. The `open_parent` function in
the wasi `fs` module was updated to avoid its own initialization of a
global preopened map and instead delegate to libc to perform this
functionality.
This should both be more robust into the future in terms of handling
path logic as well as ensuring the propened map is correctly set up at
process boot time. This does currently require some unfortunate
allocations on our side, but if that becomes an issue we can always
paper over those in time!
Remove invalid assertion back:🔗:from add_upstream_rust_crates().
This removes a misplaced assertion. The function containing the assertion is actually only ever called for upstream crates that are not considered for LTO, so we don't care whether upstream code has been merged in by LTO or not.
Fixes#59137
