Lifetimes: Infer copy dependence kind on `@noescape` closures (#88879) Follow-up to https://github.com/swiftlang/swift/pull/88733, enabling the example in rdar://172511809 ([nonescapable] Allow a nonescaping function to be a lifetime dependency source): ```swift @_lifetime(body) // Inferred dependence kind: copy func foo(body: () -> Span<Int>) { body() } ``` or ```swift // Inferred: @_lifetime(copy body) func foo(body: () -> Span<Int>) { body() } ``` Follow-up: Consider also disallowing borrow dependence on `@noescape` closures. <!-- If this pull request is targeting a release branch, please fill out the following form: https://github.com/swiftlang/.github/blob/main/PULL_REQUEST_TEMPLATE/release.md?plain=1 Otherwise, replace this comment with a description of your changes and rationale.
