PR12571: Objects of type clang::ConstantArrayType aren't always emitted with type llvm::ArrayType -- sometimes we emit them as packed structs. Don't assert if such a global array has an element type with a non-trivial destructor. llvm-svn: 155305

Remove abuse of hasTrivial*, and fix miscompile wherein global arrays with internal linkage, no uses, trivial construction, and nontrivial destruction were not emitted. llvm-svn: 167756
