[PATCH] Fix VEC_DUPLICATE simplification (PR rtl-optimization/84989)

Hi! On the following testcase, simplify_unary_operation is called on VEC_DUPLICATE from (vec_duplicate:V4SF something:SF) to V8SFmode, and simplify_unary_operation_1 tries an optimization usable for most unary operations, in particular it attempts to do (vec_duplicate:V8SF (unary:SF something:SF))
