Eric Fiselier ddfdb32b30 Implement LWG 3013 - some filesystem members should not be noexcept. ... 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. llvm-svn: 316941		2017-10-30 18:59:59 +00:00
