LWG 3013 points out that the constructors and increment members of the directory iterators need to allocate, and therefore cannot be marked noexcept. It also points out that `is_empty` and `copy` likely need to allocate as well, and as such can also not be noexcept. This patch speculatively implements the resolution removing noexcept, because libc++ does indeed have the possibility of throwing on allocation failure. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@316941 91177308-0d34-0410-b5e6-96231b3b80d8
