[PATCH 3/3] RISC-V: Add sanity testcases for RVV auto-vectorization

From: Ju-Zhe Zhong This patch adds sanity tests for basic enabling auto-vectorization. We should make sure compiler enable auto-vectorization strictly according to '-march' For example, '-march=rv32gc_zve32x' can not allow INT64 auto-vectorization. Since SEW = 64 RVV instructions are illegal ins
