structs: bugfix: crash in static slot inheritance.
* struct.c (make_struct_type): When a struct defines a static
slot that exists as an instancee slot in the supertype, there
is a crash. This is because the code assumes that the
supertype's slot is static. The index value m ends up negative
due to subtracting STATIC_SLOT_BASE from an instance slot
index, and so the code tries to copy the value of a negatively
indexed static slot from the supertype into the new static
slot. We can fix this by not doing the copy when a negative
index has been calculated. That way we treat the situation as
if the supertype didn't have that slot at all.
