  Log Message:
  -----------
  [SLP]Relax assertion about subvectors mask size

SubVectorsMask might be less than CommonMask, if the vectors with larger
number of elements are permuted or reused elements are used. Need to
consider this when estimation/building the vector to avoid compiler
crash

Fixes #117518
