ipa: Treat static constructors and destructors as non-local (PR 115815)

In PR 115815, IPA-SRA thought it had control over all invocations of a
(recursive) static destructor but it did not see the implied
invocation which led to the original being left behind and the
clean-up code encountering uses of SSAs that definitely should have
been dead.

Fixed by teaching cgraph_node::can_be_local_p about static
constructors and destructors.  Similar test is missing in
cgraph_node::local_p so I added the check there as well.
