Description
Pcard-70459
ElementwiseKernel和BroadcastKernel中使用了向量化技术，优化显存访问吞吐。如采用vec_size=4，float性能可提升约5%，float16性能可提升约30%，但是对于double等64位以上的数据类型，则没有明显的性能提升。故本PR避免对64位以上数据类型做向量化，减少编译静态库的体积。单个Ampere架构API-Benchmark Fail应与本PR无关，在https://xly.bce.baidu.com/paddlepaddle/paddle/newipipe/detail/9126824/job/23820104 也观察到呈现同样的现象。
