Rustc pull update

…O is enabled The parallel frontend makes the cookies nondeterministic in their current form, resulting in nondeterministic outputs when bitcode is emitted or LTO is used. Causes minor diagnostic regression for inline asm in release builds.

…const_check function

This updates the rust-version file to 32d94cc.

…e-test-link Update links for test-x86_64-gnu-debug and test-aarch64-gnu-debug

This test demonstrates the existing crash, and will be migrated to a successful coverage test in a subsequent commit. Co-Authored-By: Rachel Barker <rachel.barker@ferrous-systems.com>

Compile-time-only functions don't generate code, so instrumenting them for coverage is useless. This also avoids an ICE when trying to get the function's symbol name for an unused-function record, which can occur when instrumenting `core`. Co-Authored-By: Rachel Barker <rachel.barker@ferrous-systems.com>

In all cases, the caller was passing `&self.thir[scrutinee_id].span`, which can just as easily be done by the callee. There's no need to add confusion by passing a separate span.

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
