mesa/glspirv: Add struct gl_spirv_module
v2: * Make the SPIR-V module struct part of a larger gl_shader_spirv_data struct that will be introduced later, and don't reference it directly in gl_shader. (Eduardo Lima) * Readability improvements (Ian Romanick) Reviewed-by: Ian Romanick <[email protected]>
