structure fxsave* / fxsave64 changed from 102x to 11.0?

On 10.2 amd64, compilng ArcticFox i dev branch s fine.

However, on 11.0 I get this error:

167:52.84 
/home/multix/code/Arctic-Fox/js/src/wasm/WasmSignalHandlers.cpp:166:25:

&XMM_sig(context, 1);

Now... the code is a little bit old, since it is from older Firefox. But 
also I am testing on NetBSD 11.

Does this rign a bell do somebody, things that changed from 10.x to 11.x?

I wonder if something changed in the kernel headers that made the code 
incompatible? It comes from machine/fpu.h

Interestingly, if I open fpu.h, I find this comment:

/*
 * This file is only present for backwards compatibility with
 * a few user programs, particularly firefox.
