seq-mthread/pals_STARTPALS_ActiveStandby* benchmarks have suspicious self comparision

[delcypher]

Clang is emitting a lot of warnings of the same type for some very suspicious looking code in the

seq-mthread/pals_STARTPALS_ActiveStandby*.c benchmarks.

The warnings look similar to this:

pals_STARTPALS_ActiveStandby_false-unreach-call.4_1.ufo.BOUNDED-10.pals.c:320:22: warning: self-comparison always evaluates to false [-Wtautological-compare]
    s1s1_new = nomsg != nomsg && s1s1_new == nomsg ? nomsg : s1s1_new;

The author of these benchmarks should fix this.
