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 the 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.
