PR24798, buffer overflow in process_cu_tu_index

PR 24798
* dwarf.c (process_cu_tu_index): Avoid integer overflow on 64-bit
systems by casting ncols and nslots expressions to size_t.  Display
number of columns and slots before giving up due to buffer overflow.
Use %u to display unsigned ints.  Perform more pointer wrap tests.
