  -----------
  [SandboxVec][BottomUpVec] Add -sbvec-stop-bndl flag for debugging (#129132)

This patch adds a helper flag for bisection debugging. This flag
force-stops vectorization after this many bundles have been considered
for vectorization.
Using -sbvec-stop-bndl=0 will not vectorize the code at all.
