Serge Guelton be88539b85 Replace llvm::isPodLike<...> by llvm::is_trivially_copyable<...> ... As noted in https://bugs.llvm.org/show_bug.cgi?id=36651, the specialization for isPodLike<std::pair<...>> did not match the expectation of std::is_trivially_copyable which makes the memcpy optimization invalid. This patch renames the llvm::isPodLike trait into llvm::is_trivially_copyable. Unfortunately std::is_trivially_copyable is not portable across compiler / STL versions. So a portable version is provided too. Note that the following specialization were invalid: std::pair<T0, T1> llvm::Optional<T> Tests have been added to assert that former specialization are respected by the standard usage of llvm::is_trivially_copyable, and that when a decent version of std::is_trivially_copyable is available, llvm::is_trivially_copyable is compared to std::is_trivially_copyable. As of this patch, llvm::Optional is no longer considered trivially copyable, even if T is. This is to be fixed in a later patch, as it has impact on a long-running bug (see r347004) Note that GCC warns about this UB, but this got silented by https://reviews.llvm.org/D50296.
