Limiting the size of the debug_stmt/debug_insn expression is certainly
desirable, having it unbounded is bad. The question is what to do if the size
grows too much. One possibility is dropping them to the floor, another one
would be to have a way to refer to other vars that are already tracked at the
current spot. In debug info we could use DW_OP_call{2,4} to refer to those
DIEs' DW_AT_location, but AFAIK gdb doesn't handle those 2 yet.
