  Log Message:
  -----------
  Don't export symbols from clang/opt/llc if plugins are disabled.

The only reason we export symbols from these tools is to support
plugins; if we don't have plugins, exporting symbols just bloats the
executable and makes LTO less effective.

See review of D75879 for the discussion that led to this patch.
