Hi.
Following patch adds a new enum value so that we don't see following warning:
https://gcc.gnu.org/ml/gcc-patches/2018-01/msg01211.html
Apart from that I decided to not to number values of the enum as it uses
default number. Is it welcome?
Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.
Ready to be installed?

* profile-count.h (enum profile_quality): Add
profile_uninitialized as the first value. Do not number values
as they are zero based.
