Note that the testcases from PR30509 work fine with 4.2, so this appears to
be a different bug.

This ICE happens when there are unreachable blocks in cfg when
calculate_dominance_info is called. Adding delete_unreachable_blocks
before calculate_dominance_info in tree-vrp.c:identify_jump_threads fixes
this ICE (I need to check whether this does not cause other problems, though).

Confirmed. Even shorter testcase:
================================
struct A
{
virtual void foo() {}
} a;
struct B
{
~B() {}
};
struct C : B
{
A* p;
C() : p(&a) { p->foo(); }
} c;
================================
