  Log Message:
  -----------
  Revert "Revert "[CodeGen] Extend reduction support in ComplexDeinterleaving pass to support predication""

Adds the capability to recognize SelectInst that appear in the IR.
These instructions are generated during scalable vectorization for reduction
and when the code contains conditions inside the loop body or when
"-prefer-predicate-over-epilogue=predicate-dont-vectorize" is set.

This reverts commit ab09654832dba5cef8baa6400fdfd3e4d1495624.

Reason: Reapplying after removing unnecessary default case in switch expression.
