[PATCH] Simplify vec_unpack of uniform_vector_p constructors in match.pd.

This patch simplifies vec_unpack_hi_expr/vec_unpack_lo_expr of a uniform constructor or vec_duplicate operand. The motivation is from PR 105621 where after optimization, we're left with: vect_cst__21 = {c_8(D), c_8(D), c_8(D), c_8(D)}; vect_iftmp.7_4 = [vec_unpack_hi_expr] vect_cst__21; It
