[Metal] Shader output shows corrupted textures
Reproduction steps:
1. Open the attached project (ECSSample00.zip).
2. Play the 'main' scene.
- Notice a texture shape.
3. Open the "Shaders/sprite_instanced.shader" file.
4. Comment line 65: float2 uv = float2((vid&0x1) == 0 ? uv0.x : uv0.z, (vid/0x2) == 0 ? uv0.y : uv0.w)
5. Uncomment line 64: float2 uv = float2((vid&0x1) == 0 ? uv0.x : uv0.z, (vid/2) == 0 ? uv0.y : uv0.w);
6. Play the main scene again.
Actual behavior (Screenshots attached):
- Texture shape gets corrupted.
Reproduced with:
2018.1.1f1, 2018.1.9f1, 2018.2.3f1, 2018.3.0a8
Note:
Couldn't test with OpenGL: "-------- GLSL link error: ERROR: Implementation limit of 4096 (e.g., number of built-in plus user defined active uniforms components) exceeded, vertex shader uses 12300 total uniforms."

Resolution Note:
This is "HLSL" compiler issue (not in our pipeline). The "fix" is easy - just use vertexid as *uint* as it should be, otherwise HLSL compiler adds some weird code to do signed division (why 0x2 works - i guess it is treated as unsigned, at least unsigned ops are generated)
