When consuming a `Compose` expression that constructs a vector, flatten `Splat` subexpressions out into their components. Fixes gfx-rs#4581.

The GLSL frontend will take care of the desugaring, so I think it should work fine. wgpu/naga/src/front/glsl/functions.rs Line 422 in acaeb8d SPIR-V doesn't support those complex compose expressions as far as I know. |
