Fixed the global and static variables to always be in scope.
Made it so that you can create synthetic children of array
value objects. This is for creating array members when the
array index is out of range. This comes in handy when you have
a structure definition like:
struct Collection
{
uint32_t count;
Item array[0];
};
"array" has 1 item, but many times in practice there are more
items in "item_array".
This allows you to do:
(lldb) target variable g_collection.array[3]
To implement this, the get child at index has been modified
to have a "ignore_array_bounds" boolean that can be set to true.
