3bf8f094 - [6.4] Require an optimized stdlib to run CodableTests.swift (#90496)

[6.4] Require an optimized stdlib to run CodableTests.swift (#90496) **Explanation:** This test is a frequent cause of timeouts when run with a non-optimized stdlib. For now, we restrict it to require an optimized stdlib to run. **Original PRs:** https://github.com/swiftlang/swift/pull/90475 **Scope:** Test change only (and only disabling the test in specific conditions). **Issues:** rdar://178043375 **Risk:** Low. We are disabling a test configuration, so there's a small possibility that this could allow a bug to slip through that would have otherwise been discovered (e.g. if a compiler change introduced a miscompile only in non-release builds). **Testing:** N/A **Reviewers:** @Catfish-Man
