    slp: reject non-multiple of 2 laned SLP trees (PR99825)

    TWO_OPERANDS allows any order or number of combinations of + and -
operations
    but the pattern matcher only supports pairs of operations.

    This patch has the pattern matcher for complex numbers reject SLP trees
where
    the lanes are not a multiple of 2.
