Semachecking doesn't have the information of the caller of the intrinsic. While
here we require to know if caller has "avx" or not when the condition code is
[8, 31].
Considering such case:
```
#include <immintrin.h>
__attribute__((target("sse2")))
__m128 test1(__m128 a, __m128 b) {
return _mm_cmp_ps(a, b, 14); // shouldn't report error.
}
__attribute__((target("avx")))
__m128 test2(__m128 a, __m128 b) {
return _mm_cmp_ps(a, b, 14); // should report error.
}
