Make tests compatible with musl host
As an alternative to passing explicit linker all over the place I could try linking `cc` to musl gcc since this bootstraps itself.

add regression test for #60629
This bug was fixed, but I don't know which one. (I think it even doesn't matter at all).
Added a regression test.

with latest nightly it does not crash anymore, so nothing more to do.
Fixes#60629
(accidentally removed the remote branch on github, therefore GH closed the other PR.)
r? @nikomatsakis
Extend #60676 test for nested mut patterns.
At request of @centril, this commit extends the existing test added by #60676 to include nested `mut` patterns.

Fix async desugaring providing wrong input to procedural macros.
Fixes#60674.
This PR fixes a minor oversight introduced by #60535 where unused `mut` binding modes were removed from the arguments to an `async fn` (as they were added to the statement that we insert into the closure body). However, this meant that the input to procedural macros was incorrect. This removes that and instead fixes the `unused_mut` error that it avoided.

Skip codegen for one UI test with long file path
The path to this test is so long that object files produced by it hit some path length limit on Windows and linker cannot find them.
The workaround here is to skip codegen and avoid producing object files, this test doesn't need them anyway.
Identify when a stmt could have been parsed as an expr
There are some expressions that can be parsed as a statement without
a trailing semicolon depending on the context, which can lead to
confusing errors due to the same looking code being accepted in some
places and not others. Identify these cases and suggest enclosing in
parenthesis making the parse non-ambiguous without changing the
accepted grammar.
Fix#54186, cc #54482, fix#59975, fix#47287.
Clean up and add tests for slice drop shims
Adds a test for the MIR generated by `real_drop_in_place::<[T]>`. Also slightly reduces the number of statements and locals used in the shim.
r? @RalfJung
This commit removes the modification of the mutability of simple
bindings. While the mutability isn't used, it is important that it is
kept so that the input to procedural macros matches what the user wrote.
This commit also modifies the span of the binding mode so that it is
considered a compiler desugaring and won't be linted against for being
unused..
cleanup: Remove `DefIndexAddressSpace`
The scheme with two address spaces for `DefIndex` was needed in the past, but apparently not needed anymore (after removing `DefId`s from locals and `HirId`-ification).
test for #50518
It was fixed somewhere between 1.28.0 and 1.31.1
closes#50518
r? @estebank
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?
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.
