NOTE: Base classes will only be returned by `GetChildAtIndex(N)` if they have
something to show the user, i.e. they have instance variables or have base
classes that have instance variables. If a base class has no ivars, it will not
be returned. So if we are looking for a reliable way to get base classes, it is
better to use the exsting APIs on `lldb.SBType`.
The other thing is, do we want to add a `SBValue.__get_item__(self, arg)`
method to easily access base classes or members where we just return the value
of `SBValue.GetChildAtIndex(...)`? Then we can do:
```
var = lldb.frame.FindVariable('my_struct')
first_child = var[0]
```
Instead of:
```
first_child = None
if (len(value.bases) > 0)
first_child = value.bases[0]
else:
first_child = value.members[0]
```
