test for #50518
It was fixed somewhere between 1.28.0 and 1.31.1
closes#50518

Where's the best place to add this test? I *think* we want "compile-pass" for this test (no need to run a binary, and not running saves us a millisecond of process creation) , but there's no compile-pass anymore.
Should this be UI test with empty stdout, stderr and zero return code?
std: Update compiler-builtins crate
Pulls in a fix for ensuring that wasm targets have code in
compiler-builtins for `ldexp` which LLVM can generate references to.
libprofiler_builtins: Set compilation flags more correctly for C code.
In particular, set `COMPILER_RT_HAS_FCNTL_LCK` and `COMPILER_RT_HAS_ATOMICS` as appropriate. This should get rid of the various runtime warnings when executing instrumented binaries.
The build script is using a heuristic here that hopefully is sufficient for the time being.

Fixes#59531.
conditionally modify darwin targets to macosx targets with versions
We need this behavior so that Rust LLVM IR objects match the target triple for Clang LLVM IR objects. This matching then convinces the linker that yes, you really can do cross-language LTO with objects from different compilers.
The newly-added tests seem to pass locally on x86_64-unknown-linux-gnu. I haven't done a full test run or tried the new compiler in an cross-language LTO setup yet.
Adds support for .await under the existing async_await feature gate.
Moves macro-like await! syntax to the await_macro feature gate.
Removes support for `await` as a non-keyword under the `async_await`
feature.

This commit extends the logic used to determine what the expected
signature of a closure is so that it can also determine the expected
signature of a generator. This improves a diagnostic where the fn
signature was blamed instead of the generator body. It doesn't fix
fix the diagnostic for `async fn`.
This commit adds a test for the current behaviour of signature deduction
of generators when there is a type mismatch between the return type of
the function body and the signature.
rustc: Always handle exported symbols on the wasm target
Currently when linking an artifact rustc will only conditionally call
the `Linker::export_symbols` function, but this causes issues on some
targets, like WebAssembly, where it means that executable outputs will
not have the same symbols exported that cdylib outputs have. This commit
sinks the conditional call to `export_symbols` inside the various
implementations of the function that still need it, and otherwise the
wasm linker is configured to always pass through symbol visibility
lists.
The Genesis of Generic Germination
*Long had its coming been foretold: a collaborative effort with @yodaldevoid, set in motion by @jplatte, to beget a new Kind: one of a very different Sort to those that come before it. Amidst promises of ineffable powers previously thought unobtainable, few dared believe that the prophecies were true. But as they gazed upon that which claimed to be the Beginning, a few gentle sparks of hope fluttered deep within. It was not Time yet. But it was a Sign. And maybe, for some, that was enough.*
There's a long way to go, but we're at the point where we would benefit from GitHub's reviewing capabilities.
