    vect: Call vect_convert_output with the right vecitype [PR114108]

    This patch fixes a bug where vect_recog_abd_pattern called
vect_convert_output
    with the incorrect vecitype for the corresponding pattern_stmt.
    vect_convert_output expects vecitype to be the vector form of the scalar
type
    of the LHS of pattern_stmt, but we were passing in the vector form of t=
he
LHS
    of the new impending conversion statement.  This caused a skew in ABD's
    pattern_stmt having the vectype of the following gimple pattern_stmt.
