[PATCH] D30676: Add llvm::sys::fs::remove_directories()

[Zachary Turner via Phabricator via llvm-commits]

zturner created this revision.

  We have create_directories() which can create an entire tree,
  and remove(), which can remove an empty directory, but not
  a remove_directories() which can remove an entire tree.
  
  This patch adds such a function.
