Add `needs-target-has-atomic` directive
Before this commit, the test writer has to specify platforms and architectures by hand for targets that have differing atomic width support. `#[cfg(target_has_atomic)]` is not quite the same because (1) you may have to specify additional matchers manually which has to be maintained individually, and (2) the `#[cfg]` blocks does not communicate to compiletest that a test would be ignored for a given target. This commit implements a `//@ needs-target-has-atomic` directive which admits a comma-separated list of required atomic widths that the target must satisfy in order for the test to run. ``` //@ needs-target-has-atomic: 8, 16, ptr ``` See <https://github.com/rust-lang/rust/issues/87377>.
