Revert "[libc++] Always build c++experimental.a"
This caused build failures when building Clang and libc++ together on Mac:
fatal error: 'experimental/memory_resource' file not found
See the code review for details. Reverting until the problem and how to
solve it is better understood.
(Updates to some test files were not reverted, since they seemed
unrelated and were later updated by 340b48b267b96.)
