[Legalizer] Only allocate the SetVectors once per function. Prior to this patch we used to create SetVectors in temporaries that were created and destroyed for each instruction. Now, instead we create and destroyed them only once, but clear the content for each instruction. This speeds up the pass by ~25%.
