Log:
  Pull in r353907 from upstream llvm trunk (by Reid Kleckner):

    [MC] Make symbol version errors non-fatal

    We stil don't have a source location, which is pretty lame, but at
    least we won't tell the user to file a clang bug report anymore.

    Fixes PR40712

  This will make errors for symbols with @@ versions that are not defined
  non-fatal.  For example:

    void f(void)
    {
      __asm__(".symver foo,bar@@baz");
    }

  will now result in:

    error: versioned symbol bar@@baz must be defined

  instead of clang crashing with a diagnostic report.

  PR:           234671
  Upstream PR:  https://bugs.llvm.org/show_bug.cgi?id=40712
  MFC after:    3 days

Changes:
  head/contrib/llvm/lib/MC/ELFObjectWriter.cpp
