ipa/120146 - deal with vanished varpool nodes in IPA PTA

I don't understand why they vanish when still refered to, but
lets deal with that in a conservative way.

PR ipa/120146
* tree-ssa-structalias.cc (create_variable_info_for): If
the symtab cannot tell us whether all refs to a variable
are explicit assume they are not.

* g++.dg/ipa/pr120146.C: New testcase.
