    tree-optimization/111125 - avoid BB vectorization in novector loops

    When a loop is marked with

      #pragma GCC novector

    the following makes sure to also skip BB vectorization for contained
    blocks.  That avoids gcc.dg/vect/bb-slp-29.c failing on aarch64
    because of extra BB vectorization therein.  I'm not specifically
    dealing with sub-loops of novector loops, the desired semantics
    isn't documented.

            PR tree-optimization/111125
            * tree-vect-slp.cc (vect_slp_function): Split at novector
            loop entry, do not push blocks in novector loops.=
