Improve DCE of dead parts of a permute chain
gcc.dg/vect/bb-slp-pr78205.c is reported to have regressed with
the PR113073 change and in the end it's due to the DCE performed
by vect_transform_slp_perm_load_1 being imperfect. The following
enhances it to also cover the CTOR and VIEW_CONVERT operations that
might be involved.
* tree-vect-slp.cc (vect_transform_slp_perm_load_1): Also handle
CTOR and VIEW_CONVERT up to the load when performing chain DCE.
