Elena Demikhovsky 376a18bd92 [Loop Vectorizer] Handling loops FP induction variables. 
Allowed loop vectorization with secondary FP IVs. Like this:
float *A;
float x = init;
for (int i=0; i < N; ++i) {
  A[i] = x;
  x -= fp_inc;
}

The auto-vectorization is possible when the induction binary operator is "fast" or the function has "unsafe" attribute.
