[libc++] Lift std::errc into a separated header
Summary: This is needed to implement `<charconv>`, otherwise `<charconv>` would need to include `<system_error>`, which pulls in `<string>` -- a header which the `<charconv>` proposal intends to keep away from. Reviewers: mclow.lists, EricWF Reviewed By: mclow.lists Subscribers: christof, cfe-commits Differential Revision: https://reviews.llvm.org/D41347 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@336164 91177308-0d34-0410-b5e6-96231b3b80d8
