f640438b40 Keep info on pre-desugaring expression for better "incorrect .await" suggestion 
Keep the `HirId` of `.await`ed expressions so in the case of a `fn` call
on on a sync `fn`, we can suggest maybe turning it into an `async fn`.

a737592a3d Auto merge of #91654 - nikic:llvmbc-section-flags, r=nagisa 
Use module inline assembly to embed bitcode

In LLVM 14, our current method of setting section flags to avoid
embedding the `.llvmbc` section into final compilation artifacts
will no longer work, see issue #90326. The upstream recommendation
is to instead embed the entire bitcode using module-level inline
assembly, which is what this change does.

I've kept the existing code for platforms where we do not need to
set section flags, but possibly we should always be using the
inline asm approach (which would have to look a bit different for MachO).

4a7fb971c9 Auto merge of #91569 - erikdesjardins:vt-align, r=nikic 
Attach range metadata to alignment loads from vtables

...because alignment is always nonzero[0].

This helps eliminate redundant runtime alignment checks, when a DST
is a field of a struct whose remaining fields have alignment 1.

Fixes #91438.

---
[0]:

The [reference](https://doc.rust-lang.org/reference/type-layout.html) says that alignment must be at least 1.

And in practice, the alignment field for all vtables is generated here: 772d51f887/compiler/rustc_middle/src/ty/vtable.rs (L68-L90) and is nonzero because [`Align::bytes()`](772d51f887/compiler/rustc_target/src/abi/mod.rs (L547-L549)) is always nonzero.

3f2a1c9c17 Use OutputFilenames to generate output file for -Zllvm-time-trace 
The resulting profile will include the crate name and will be stored in
the `--out-dir` directory.

This implementation makes it convenient to use LLVM time trace together
with cargo, in the contrast to the previous implementation which would
overwrite profiles or store them in `.cargo/registry/..`.

6bda5b331c Auto merge of #90716 - euclio:libloading, r=cjgillot 
replace dynamic library module with libloading

This PR deletes the `rustc_metadata::dynamic_lib` module in favor of the popular and better tested [`libloading` crate](https://github.com/nagisa/rust_libloading/).

We don't benefit from `libloading`'s symbol lifetimes since we end up leaking the loaded library in all cases, but the call-sites look much nicer by improving error handling and abstracting away some transmutes. We also can remove `rustc_metadata`'s direct dependencies on `libc` and `winapi`.

This PR also adds an exception for `libloading` (and its license) to tidy, so this will need sign-off from the compiler team.

This no longer works now that asm! needs an explicit import. Also, it's
been over a year since asm! landed, everyone should have transitioned by
now.
