Re: [PATCH 0/2] MR302: vkd3d-shader/hlsl: Allow 'const' modifier without initializer in the global scope.

[Francisco Casas (＠fcasas)]

I find no problem with the series. Maybe I would add a test for const arguments, but that doesn't stop working because of the changes:

```hlsl
float4 main(const float a : SEM) : sv_target
{
    return a + 1;
}
```

By the way, this a little silly, but it seems that while native compiler doesn't allow to assign to a const lhs with `=`, it surprisingly does allow assignments with operators such as `+=`. The value is not updated in this case though:

```hlsl
float4 main() : sv_target
{
    const float4 f = {1, 2, 3, 4};

    f += 3;
    return f;
}
```
```
ps_4_0
dcl_output o0.xyzw
mov o0.xyzw, l(1.000000,2.000000,3.000000,4.000000)
ret
```
