    tree-optimization/105312 - fix ISEL VCOND expansion

    The following aligns ISEL VEC_COND_EXPR expansion using VCOND
    with the optab query done by vector lowering.  Instead of only
    allowing the signed optab to provide EQ/NE compares we allow both
    here though since there seems to be no documented canonicalization.
