Weird positioning/corruption with Haswell

Also try changing int sse2 = has_sse2(); to int sse2 = 0;, and combinations with disabling avx.

Well, I checked if libass was correctly detecting SSE2 and AVX2 with:

int sse2 = has_sse2();
int avx2 = has_avx2();
if (sse2) puts("\n --- LIBASS HAS SSE2 ---\n");
if (avx2) puts("\n --- LIBASS HAS AVX2 ---\n");

It definitely detects both on my laptop. int sse2 = 0; has no effect, but setting both int avx2 = 0; and int sse2 = 0; fixes the problem. I guess the issue is triggered by both the SSE2 and AVX2 code, but only on Haswell.

Also, changing line 78 to priv->be_blur_func = be_blur_c; fixes the problem.

Should be fixed by 9539ecc; could you test?

I'm getting build errors with that commit.

It works! Thanks.
