Since our error_category is based on the std one, we should have the same visibility for the constructor. This also allows us to avoid using the _do_message implementation detail in our own categories. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203998 91177308-0d34-0410-b5e6-96231b3b80d8
