After teaching VN to handle internal functions we now optimize
the redundant inner loop preheader check of the testcase making
the dump scanning fail because there's nothing to predict left.
The following restores the inner preheader check by making it
not redundant.
Tested on x86_64-unknown-linux-gnu, pushed.

* gfortran.dg/predict-2.f90: Adjust to avoid redundant
inner loop preheader checking code.
