This is a workaround for an issue in SPIRV-Optimizer. When optimizing
large shaders the optimizer can crash. This can be fixed by altering the
maximum object ids and performing a compact ids in the end. However this
part of the API is not accessible via ShaderC.
To work around the issue shader optimizations are being disabled for
large shaders. The issue has been reported upstream.
