Original change's description:
> Add support for top-level uniforms in SPIR-V.
>
> Previously, a uniform not wrapped in an interface block would report a
> SPIR-V error:
>
> "Variables identified with the Uniform storage class are
> used to access transparent buffer backed resources. Such variables must
> be typed as OpTypeStruct, or an array of this type..."
>
> Now, the SPIR-V code generator automatically detects such global
> variables and synthesizes a struct named _UniformBuffer to hold them.
> When these variables are accessed, an OpAccessChain instruction is added
> to grab the variable out of the struct.
