Implement the proposed semantics from P1164R0, which reverts the changes
of LWG 2935. This means that failure to create a directory because a
non-directory already exists with that name will be reported as an

While rewriting the function, also fix PR 87846, which is a result of

unless it gets used in that translation unit. Other translation units
