PR25070, SEGV in function _bfd_dwarf2_find_nearest_line
Evil testcase with two debug info sections, with sizes of 2aaaabac4ec1
and ffffd5555453b140 result in a total size of 1. Reading the first
section of course overflows the buffer and tramples on other memory.
PR 25070
* dwarf2.c (_bfd_dwarf2_slurp_debug_info): Catch overflow of
total_size calculation.
