  From: Ju-Zhe Zhong <juzhe.zhong@rivai.ai>

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 instructions in this situation.

Also, testing auto-vectoriztion for all combinations of LMUL = 1/2/4/8
gcc/testsuite/ChangeLog:

Just #include "stdint-gcc.h", don't include stdint.h if possible since
it will got trouble on glibc.
