tree-optimization/98113 - vectorize a sequence of BIT_INSERT_EXPRs
This adds the capability to handle a sequence of vector BIT_INSERT_EXPRs
to be vectorized similar as to how we vectorize vector constructors.

PR tree-optimization/98113
* tree-vectorizer.h (struct slp_root): New.
(_bb_vec_info::roots): New member.
* tree-vect-slp.c (vect_analyze_slp): Also walk BB info
roots.
(_bb_vec_info::_bb_vec_info): Adjust.
(_bb_vec_info::~_bb_vec_info): Likewise.
(vld_cmp): New.
(vect_slp_is_lane_insert): Likewise.
(vect_slp_check_for_constructors): Match a series of
BIT_INSERT_EXPRs as vector constructor.
(vect_slp_analyze_bb_1): Continue if BB info roots is
not empty.
(vect_slp_analyze_bb_1): Mark the whole BIT_INSERT_EXPR root
sequence as pure_slp.
* gcc.dg/vect/bb-slp-70.c: New testcase.
