Igor Kirillov 04a8070b46 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.

Differential Revision: https://reviews.llvm.org/D152558

This reverts commit ab09654832.

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