A number of tests exercise features only available in Apple OSes that shipped with Swift 5.0 in the OS; this includes the following versions: - macOS 10.14.4 - iOS 12.2 - tvOS 12.2 - watchOS 5.2 Previously these tests were restricted to running on macOS only, with an explicit -target x86_64-apple-macosx10.14.4. To get better test coverage, add a new %target-stable-abi-triple substitution which expands to a triple with the correct OS version on all Apple platforms. On non-Apple platforms, this is the same as %target-variant-triple, but for now any test that uses this exercises Apple platform features anyway. One caveat is that since iOS 12.2 does not have a 32-bit slice, we have to skip any tests that use -target %target-stable-abi-triple on this platform. A new swift_stable_abi feature flag can be tested with 'REQUIRES: swift_stable_abi'. To get maximum test coverage, I split off a 'stable_abi' version of a few tests that build with both an old and new deployment target. This allows the old deployment target case to still be tested on 32-bit iOS.
