The main highlight this sync is improved support for inline assembly. Thanks @nbdd0121! Inline assembly is still disabled by default for builds in the main rust repo though. Cranelift will now also be built from the crates.io releases rather than the git repo. Git repos are incompatible with vendoring.

These were left over in migrations to subtrees, which should generally be treated
as-if it was local.

Also fixes a warning caused by this change.

Nothing exciting this time. Mostly internal refactorings.

This version no longer has the old x86 backend
Turn vtable_allocation() into a query

This PR removes the untracked vtable-const-allocation cache from the `tcx` and turns the `vtable_allocation()` method into a query.

The change is pretty straightforward and should be backportable without too much effort.

Fixes rust-lang#89598.
As per the libs team decision in rust-lang#58935.

Closes rust-lang#58935

Instead use the default_call_conv field on TargetFrontendConfig to get
the default CallConv.
Remove `SymbolStr`

This was originally proposed in rust-lang#74554 (comment). As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences.

Best reviewed one commit at a time.

Git repos are incompatible with vendoring.

What do you mean? https://doc.rust-lang.org/cargo/commands/cargo-vendor.html#description

This cargo subcommand will vendor all crates.io and git dependencies for a project into the specified directory at .

They are incompatible with the current vendoring implementation in rustbuild at least. See #90764.
