// Even if clang (and gcc) has these intrins available, you must enable them globally, unlike see for some fucking reason.
// I mean, we can do runtime branching around SSE4 paths no problem. Why all of a sudden am i being gated out of the intrins im electing to use by hand?
// No, you (the compiler) may not use these in your baseline feature set (or incl in stl locks). Yes, i still want them. Now fuck off.
// If these end up being wrong, blame clang and gnu for being cunts, not me.
No, I will not raise our requirements above ivybridge; no, I will not expose feature macros to the STL (et al) that boosts our requirements to modern intelaviv slop and amd atomic ackers
