[Bug 50927] Conspiracy's Clean Slate 64K demo crashes due to missing 'all' handling

--- Comment #5 from Nikolay Sivov  ---
This function is implemented here
https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/97. next issue will be
about picking correct overloaded function, or any overloaded function at all.

The shader defines user function like this:

int func(int2 arg1, int2 arg2) {}

and calls it with int2 for first argument, but float4 for second. That
apparently works fine on Windows, prints a warning about vector truncation but
compiles.
