Merge commit f97936fab from llvm git (by Eric Fiselier):
[libc++] Cleanup and enable multiple warnings. Too many warnings are being disabled too quickly. Warnings are important to keeping libc++ correct. This patch re-enables two warnings: -Wconstant-evaluated and -Wdeprecated-copy. In future, all warnings disabled for the test suite should require an attached bug. The bug should state the plan for re-enabling that warning, or a strong case why it should remain disabled. This should fix a number of new g++ 9 warnings. Requested by: rlibby MFC after: 3 days
