I wrote an assembly routine to emulate the intrinsic function

This function ensures the compiler that it's first argument is always even and
always in range [0...second argument]. So compiler allowed to generate case as
efficient table jump without additional checking of switch() statement.
And nothing more. You can just replace
switch(__even_in_range(ADC12IV,34))
to
switch(ADC12IV).
