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.
