tree-optimization/105175 - avoid -Wvector-operation-performance
This avoids -Wvector-operation-performance diagnostics for vectorizer
produced code. It's unfortunate the warning_at code in
tree-vect-generic.cc needs adjustments but the diagnostic suppression
code doesn't magically suppress those otherwise.
