[PATCH 0/4] MR518: vkd3d-shader: Enable sm1 -> spirv compilation.

[Zebediah Figura (＠zfigura)]

```
    Datta: what have we given?
    My friend, blood shaking my heart
    The awful daring of a moment's surrender
    Which an age of prudence can never retract
    By this, and this only, we have existed
    Which is not to be found in our obituaries
    Or in memories draped by the beneficient spider
    Or under seals broken by the lean solicitor
    In our empty rooms
```
