This is necessary to accommodate ARM64EC, under which CONTEXT refers to the

v3: Better split.
Sorry, one detail I missed to point out last time:
+ typedef struct DECLSPEC_ALIGN(16)
+#ifdef _ARM64_
+ _CONTEXT
+#else
+ _ARM64_NT_CONTEXT
+#endif
+ {
Why is this being conditional here? For e.g. _ARM64_NT_NEON128 above, we
unconditionally name the type _ARM64_NT_NEON128, and then add a typedef if
we want to use a shorter form.
Is this because there may be code out there that does "struct _CONTEXT",
and this doesn't work if we rename the actual underlying (non-typedef)
struct name? But there's less risk of anybody doing this with "union
_NEON128"?
