When `NonisolatedNonsendingByDefault` is enabled, overload resolution of `ExitTest.__store()` picks the overload that takes any old `T` instead of taking a function. This overload exists only to suppress certain unhelpful compiler diagnostics and its implementation immediately aborts, which causes the described failure. Adding `nonisolated(nonsending)` or `@concurrent` to the "good" overload doesn't appear to satisfy the type checker, so mark the "bad" overload as explicitly disfavoured instead. Resolves #1375.

The CI failure we're seeing is due to a regression in the 6.3 compiler (which is being used to build this branch despite us targetting 6.2.2, such is life.) We believe the regression is resolved by swiftlang/swift#85410, but that isn't in a toolchain yet. The regression does not affect 6.2.2 itself. |

#1421) - **Explanation**: Adjust the (non-ABI-affecting) signature of an underlying function used by the expansion of the `#expect(processExitsWith:)` macro so that when Approachable Concurrency is enabled, we pick the correct overload of said function. - **Scope**: Exit tests with Approachable Concurrency enabled. - **Issues**: #1375 - **Original PRs**: #1383, #1407 - **Risk**: Low - **Testing**: Existing CI jobs and manual verification. It is not possible at this time to write a unit test for this fix due to swiftlang/swift-package-manager#9293. - **Reviewers**: @grynspan @briancroom @jerryjrchen
