This patch implements P0430R2, who's largest change is adding the path::format enumeration for supporting path format conversions in path constructors. However, since libc++'s filesystem only really supports POSIX like systems, there are no real changes needed. This patch simply adds the format enum and then ignores it when it's passed to constructors. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@329031 91177308-0d34-0410-b5e6-96231b3b80d8
