[committed] Mention DIE counting phase with --devel-trace

[Tom de Vries <tdevries@suse.de>]

Hi,

Now that DIE counting is an additional phase, mention it in the trace:
...
 $ cp cc1 1; time.sh dwz 1 --devel-trace
 Compressing 1
+Counting DIEs
 Hit low-mem die-limit
 Compressing 1 in low-mem mode
 maxmem: 655324
 real: 9.81
 user: 9.53
 system: 0.27
...

Which makes it also clear when we're not using that phase:
...
$ cp cc1 1; time.sh dwz 1 -l11000000 --devel-trace
Compressing 1
maxmem: 1177616
real: 5.89
user: 5.55
system: 0.33
...

Committed to trunk.

Thanks,
- Tom
