The change in 07f855d781 introduced a
trailing numeral of some kind after the `extern crate
compiler_builtins`, which appears to have caused at least two false
negatives (654b924 and 657fd24). Instead, this change normalizes the
test output to ignore the number (of symbols rustc recognizes?) to avoid
needing to re-`--bless` these two tests for unrelated changes.
This patch adds a feature gate `async_fn_track_caller` that is separate from `closure_track_caller`. This is to allow enabling `async_fn_track_caller` separately.
Fixes#110009
This crate is a private implementation detail. We only need to insert it
into the crate graph for linking and should not expose any of its public
API.
