Free up some space in lldb_private::Block by not requiring a sibling pointer.
The old way of storing blocks used to use the sibling pointer, but now all
blocks contain a collection of shared pointers to blocks so this isn't required
anymore and a parent can be asked to find the sibling block for a child block.
