Hi,
while working on allocator reorg for summaries I noticed that
we never initialize statics_read in ipa-reference which is later used to
bookkeep the strongly connected components.  I am bit surprised that
this ever worked w/o crashing, but it seems to be the case.

Bootstrapped/regteted x86_64-linux, comitted.
