Only delete regular files and directories.
This ports a missing feature from PathV1.h. I am not sure how to test this with the regular infrastructure, but an Apple bot should check this when r183985 is reapplied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184119 91177308-0d34-0410-b5e6-96231b3b80d8
