+ __cpuid (function == 4) requires subfunction number in ECX.
+ MSDN: The __cpuid intrinsic clears the ECX register before calling the cpuid instruction.
+ __cpuid() in new MSVC clears ECX.
+ __cpuid() in old MSVC (14.00) doesn't clear ECX
+ We still can use __cpuid for low (function) values that don't require ECX,
+ but __cpuid() in old MSVC will be incorrect for some function values: (function == 4).
+ So here we use the hack for old MSVC to send (subFunction) in ECX register to cpuid instruction,
+ where ECX value is first parameter for FAST_CALL / NO_INLINE function,
+ So the caller of MY__cpuidex_HACK() sets ECX as subFunction, and
+ old MSVC for __cpuid() doesn't change ECX and cpuid instruction gets (subFunction) value.
+
+ DON'T remove MY_NO_INLINE and MY_FAST_CALL for MY__cpuidex_HACK() !!!
