  -----------
  [X86] combineINSERT_SUBVECTOR - directly fold to X86ISD::SUBV_BROADCAST_LOAD to prevent vector split infinite loop (#145077)

This reverts #140919 / f1d03dedfbe87119cfcafb07e0e0f90ec291cb97 - which
could result in another fold trying to split the concatenation apart
again before it was folded to a SUBV_BROADCAST_LOAD
