This PR updates our parsing of the `@available` attribute during expansion of the `@Test` and `@Suite` macros to support custom availability domains of the form: ```swift @available(Foo) @test func f() {} ``` This change means the macro expansion will include `if #available(Foo)` instead of `if #available(Foo, *)` in this case. Resolves rdar://160323829.
