gdb/dwarf2read.c: Sanity check DW_AT_sibling values.
When reading objects with corrupt debug information it is possible that
the sibling chain can form a loop, which leads to an infinite loop and
memory exhaustion.
Avoid this situation by disregarding and DW_AT_sibling values that point
to a lower address than the current entry.
