Under closer inspection, the change to simplejump_p is causing
problems with cross-jumping.
The cross-jump code really expects an unconditional branch to
have no side effects of any kind. All it is in effect is a
brute-force substring comparison, and it expects to be able
to break the string at any point without regard to life info.
We'll have to come up with another solution to cure the new
target's flow and ifcvt aborts.
