  Log Message:
  -----------
  [LV] Use separate index to access StoredValues in vectorizeInterleave.

StoredValues only has entries for members of the interleave group. If
there are gaps, then using the index i here will either access a wrong
entry or be out-of-bounds.

Instead use a dedicated index that only gets incremented for members of
the interleave group.

Fixes #59090.
