  Changed paths:
    M lld/ELF/Driver.cpp
    A lld/test/ELF/lto/init-fini.ll

  Log Message:
  -----------
  Keep symbols passed by -init and -fini

Previously, symbols passed by -init and -fini look as if they are
not referenced by anyone, and the LTO might eliminate them.
This patch fixes the issue.
