Invalid arithmetic in compute shader when multiplying with uint value
Reproduction steps:
1. Open the user's attached project
2. Select DEBUG/Dispatch shader
3. Observe the Console window
Expected result: "modulo*8 = 24" is printed
Actual result: "modulo*8 = 8" is printed
Reproducible with: 2018.4.32f1, 2019.4.22f1, 2020.3.1f1, 2021.1.0f1, 2021.2.0a10

Resolution Note (2021.2.X):
Unfortunately this is a bug in the FXC shader compiler which is a black box to us and therefore can't fix it. Fortunately the repro case already presents couple of different workarounds (casting to int and using immediate value instead of a uniform). E.g. touching the calculation in a way that prevents the compiler choosing the flawed path.
