Which cycles rendering pass is antialiased In all render passes that Blender Cycles support, which one are antialiased and which one is not by default. And, if possible, how can I turn all the anti-aliasing for all of them completely? I got know before that Mist passed is anti-aliasing, Z-buffer is not (correct me if I'm wrong).

Here are the list of the other render passes:

Diffuse Direct, Indirect, Color

Glossy Direct, Indirect, Color

Transmission Direct, Indirect, Color

Subsurface Direct, Indirect, Color

Emission

Environment

Shadow

Ambient Occlusion

Normal

Vector

Object Index

Material Index
You need to know, that there is nonstandard algorithm to get anti-aliasing in cycles instead normal render. Each pass in cycles also is an anti-aliasing pass too. Each pass specifies the color, shadow and antialiasing at same time:



And cycles has a setting to manipulate how far each pixel sample can deviate to get anti-aliasing: 



Making the filter size value smaller will squeeze the samples more into the center. So there is no option to turn off anti-aliasing, but you can make filter size at minimum to get similar result:
