This fixes pr25569.

Basically it's possible for biv_p to return true, but
iv_analyze_result may be unable to analyze the biv.  While it's
desirable for iv_analyze_result to handle everything for which
biv_p returns true, according to Zdenek fixing that is going to
be nontrivial.

In the mean time it is safe to give up splitting variables
for which biv_p returns true, but iv_analyze_result returns false.

Bootstrapped and regression tested i686-pc-linux-gnu and I verified
the patch fixes the ICE on a ppc64 cross compiler.
