m_disassembly_range was used only to prune the list of breakpoints to those
that are in the current function. This isn't really necessary, as the list is
only used to highlight instructions with breakpoints on them, and an unpruned
list works just as well for that.
The shouldn't make things slower, since we still needed through iterate through
all breakpoints to create the list, and I doubt anyone will notice the memory
used to store the extra breakpoints.
