With enough codegen complete, we can now correctly report the size of vector registers for LSX/LASX, allowing auto vectorization (The `auto-vec` feature needs to be enabled simultaneously). As described, the `auto-vec` feature is an experimental one. To ensure that automatic vectorization is not enabled by default, because the information provided by the current `TTI` cannot yield additional benefits for automatic vectorization.
