This patch removes some vendor-specific availability XFAILs from the test suite. In the future, when a new feature is introduced in the dylib, an availability macro should be created and a matching lit feature should be created. That way, the test suite can XFAIL whenever the implementation lacks the necessary feature instead of being cluttered by vendor-specific annotations. Right now, those vendor-specific annotations are still somewhat cluttering the test suite by being in `config.py`, but at least they are localized. In the future, we could design a way to define those less intrusively or even automatically based on the availability macros that already exist in <__config>. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@353201 91177308-0d34-0410-b5e6-96231b3b80d8
