[Bug tree-optimization/26939] loop number of iterations analysis confused by what PRE did (PRE is doing its job)

Note that the patch for 23855 will only help for invariant conditions in the
loop header, while the problem exists also for non-invariant ones.  So, as
Danny notes, SCEV should be improved to maybe handle this case.
