Hi,
Because we switch intrinsics for avx512bf16 to the new type __bf16. Now we
could use m128/256bh for vector bf16 type instead of m128/256bf16.
And unified builtin for avx512bf16/avxneconvert.
Thanks,
Lingling

The following adjusts the testcase to require no epilogue also
for larger vectors than V4SI.
Pushed.

2. In the vtv_malloc.cc file __vtv_malloc_init function, it does not check
whether VTV_PAGE_SIZE is equal to the
