Jonas Devlieghere df8e291ef9 [FileSpec] Re-implmenet removeLastPathComponent ...

When reading DBGSourcePathRemapping from a dSYM, we remove the last two
path components to make the source lookup more general. However, when
dealing with a relative path that has less than 2 components, we ended
up with an invalid (empty) FileSpec.

This patch changes the behavior of removeLastPathComponent to remove the
last path component, if possible. It does this by checking whether a
parent path exists, and if so using that as the new path. We rely
entirely on LLVM's path implementation to do the heavy lifting.

We now also return a boolean which indicates whether the operator was
successful or not.
