[PATCH] Print die_hash2 for --odr --devel-dump-dies

[Tom de Vries]

Hi,

For --odr, there's an additional hash value, die->u.p1.die_hash2.

Print this with --devel-dump-dies, such that we have:
...
$ dwz --devel-dump-dies --odr odr-struct
  114 O f56004ac(cd46c7ab) f56004ac aaa structure_type
  ...
  1ba O f56004ac(cd46c7ab) f56004ac aaa structure_type
...

Used to debug PR27400.

Any comments?

Thanks,
- Tom
