From: Andi Kleen <a...@linux.intel.com>
The pass to transform gimple based on value profiling runs with autofdo
on, but currently every transformation fails. For indirect calls autofdo
does it on its own, and it doesn't suppport other value profiling. So don't
run this pass when autofdo is active. This also avoids bogus
dump file entries.

* 2016-06-26 Andi Kleen <a...@linux.intel.com>
* value-prof.c (gimple_value_profile_transformations): Don't run
when auto_profile is on.
