Summary: As discussed on lldb-dev, this patch moves some LLDB tests into a hierarchy that more closely resembles the commands we use in the LLDB interpreter. This patch should only move tests that use the command interpreter and shouldn't touch any tests that primarily test the SB API.

Test calling an overriden method.
|
|
|
|
Note:
|
|
This verifies that LLDB is correctly building the method overrides table.
|
|
If this table is not built correctly then calls to overridden methods in
|
|
derived classes may generate references to non-existant vtable entries,
|
|
as the compiler treats the overridden method as a totally new virtual
|
|
method definition.
