The following removes the ability to switch back to non SLP-only
operation of the vectorizer - a requirement to start cleaning out
non-SLP paths without risk of regressing that case.

        * params.opt (--param=vect-force-slp): Remove.
        * doc/invoke.texi (--param=vect-force-slp): Likewise.
        * tree-vect-loop.cc (vect_analyze_loop_2): Assume
        param_vect_force_slp is 1.
        * tree-vect-stmts.cc (vect_analyze_stmt): Likewise.
