[committed] Add --devel options to usage message

[Tom de Vries]

Hi,

Mention --devel-options in usage message if compiled with -DDEVEL:
...
$ make CC="gcc -DDEVEL"
$ ./dwz -?
./dwz: Usage:
  dwz [-v] [-q] [-l <COUNT|none>] [-L <COUNT|none>] [-h] [-m COMMONFILE] [-M NAME] [-r] [FILES]
  dwz [-v] [-q] [-l <COUNT|none>] [-L <COUNT|none>] -o OUTFILE FILE
Development options:
  --devel-trace
  --devel-ignore-size
  --devel-ignore-locus
  --devel-save-temps
  --devel-dump-dies
  --devel-unoptimized-multifile
  --devel-verify-edges
  --devel-dump-edges
  --devel-partition-dups-opt
  --devel-die-count-method
...

Committed to trunk.

Thanks,
- Tom
