When writting symtab_real_symbol_p I made external nodes to not be real symbols
unless they are explicitelly called or refereed.
The reason is that we keep around virtual extenral functions for possible
devirtualization and I did not want those symbol appear to refereed in
lto-plugin symbol table. While this works well with lto-plugin symbol table
output it does not fare well with the use in lto-symtab.
I am testing patch to separate both predicates.
