This is already handled by supported_types().

The previous approach of checking for the reserve-r9 target feature
didn't actually work because LLVM only sets this feature very late when
initializing the per-function subtarget.

Checking of asm! register operands now properly takes function
attributes such as #[target_feature] and #[instruction_set] into
account.

Metadata::modified works in all platforms supported by the filetime
crate. This changes brings rustbuild a tiny bit closer towards dropping
the filetime dependency.

Some improvements to the async docs

The goal here is to make the docs overall a little bit more comprehensive and add more links between the things.

One thing that's not working yet is the links to the keywords. Somehow I couldn't get them to work.

r? ``@GuillaumeGomez`` do you know how I could get the keyword links to work?

Ensure stability directives are checked in all cases

Split off  rust-lang#93017

Stability and deprecation were not checked in all cases, for instance if a type error happened.
This PR moves the check earlier in the pipeline to ensure the errors are emitted in all cases.

Gracefully handle non-UTF-8 string slices when pretty printing

Fixes rust-lang#78520.

Fix several asm! related issues

This is a combination of several fixes, each split into a separate commit. Splitting these into PRs is not practical since they conflict with each other.

Fixes rust-lang#92378
Fixes rust-lang#85247
