* @brief Disables the AVX sanity check.
*
* Don't compile xxh_x86dispatch.c with options like `-mavx*`, `-march=native`,
* or `/arch:AVX*`. It is intended to be compiled for the minimum target, and
* it selectively enables SSE2, AVX2, and AVX512 when it is needed.
*
* Using this option _globally_ allows this feature, and therefore makes it
* undefined behavior to execute on any CPU without said feature.
*
* Even if the source code isn't directly using AVX intrinsics in a function,
* the compiler can still generate AVX code from autovectorization and by
* "upgrading" SSE2 intrinsics to use the VEX prefixes (a.k.a. AVX128).
*
* Use the same flags that you use to compile the rest of the program; this
* file will safely generate SSE2, AVX2, and AVX512 without these flags.
*
* Define XXH_X86DISPATCH_ALLOW_AVX to ignore this check, and feel free to open
* an issue if there is a target in the future where AVX is a default feature.
