Attribute specifying the address point within a C++ virtual table (vtable).
The `index` (vtable index) parameter identifies which vtable to use within a
vtable group, while the `offset` (address point index) specifies the offset
within that vtable where the address begins.
Example:
```mlir
cir.global linkonce_odr @_ZTV1B = ...
...
%3 = cir.vtable.address_point(@_ZTV1B, address_point = <index = 0, offset =
2>)
: !cir.ptr<!cir.ptr<() -> i32>>
```
```
