  Changed paths:
    M lld/MachO/LTO.cpp
    A lld/test/MachO/invalid/invalid-lto-object-path.ll
    M lld/test/MachO/lto-object-path.ll

  Log Message:
  -----------
  [lld-macho] Handle filename being passed in -lto_object_path

Clang passes a filename rather than a directory in -lto_object_path when
using FullLTO. Previously, it was always treated it as a directory, so
lld would crash when it attempted to create temporary files inside it.

Fixes #54805
