[PATCH vkd3d v4 2/6] tests: Test a number of simple HLSL operations.

Hi, I found something that I am not sure if it may be a problem:

The native compiler output is
---
ps_4_0
dcl_output o0.xyzw
mov o0.xyzw, l(20.000000,4294967296.000000,75.000000,0)
ret
---

Probably because float doesn't have enough precision to represent 4294967300.

Same for the next test:

And this one:

Everything else seems okay.
