[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.
