  -----------
  [SLP][TTI]Improve detection of the insert-subvector pattern for SLP. (#74749)

SLP vectorizer passes the type of the subvector and the mask, which size
determines the size of the resulting vector. TTI should support this
pattern to improve cost estimation of the insert_subvector shuffle
pattern.
