[PATCH] D13314: Enable -Wdeprecated in the cmake build now that LLVM (& Clang, Polly, and LLD) are -Wdeprecated clean

This particularly helps enforce the C++ Rule of 5 (for new move ops this
is already an error, but for a type only using C++98 features (copy
ctor/assign, dtor) it is only deprecated, not invalid)
