Jonas Paulsson ca520592c0 [Clang FE, SystemZ] Don't add "true" value for the "mnop-mcount" attribute. 
Let the "mnop-mcount" function attribute simply be present or non-present.
Update SystemZ backend as well to use hasFnAttribute() instead.

Jonas Paulsson 6e504d7706 [SystemZ] Recognize mnop-mcount in backend 
With -pg -mfentry -mnop-mcount, a nop is emitted instead of the call to
fentry.
