CodeGen: Start using inrange annotations on vtable getelementptr.

Authored by pcc on Sep 9 2016, 2:42 PM.



This annotation allows the optimizer to split vtable groups, as permitted by
a change to the Itanium ABI that prevents compilers from adjusting virtual
table pointers between virtual tables.

Depends on D22296
