Replaced all the fatal_errors with error_at in tree-vect-loop.c

2012-12-18  Balaji V. Iyer  <balaji.v.iyer@intel.com>

        * tree-vect-loop.c (vect_determine_vectorization_factor): Replaced all
        occurances of "fatal_error" with error_at with vect_location.
        (vect_analyze_loop_form): Likewise.
        (vect_analyze_loop_operations): Likewise.
        (vect_analyze_loop): Likewise.
