Swift shader needs a way to inline all functions, even those marked as DontInline. See https://github.com/KhronosGroup/SPIRV-Tools/pull/4471. This implements the suggestion I made in the PR. We add a pass that will remove the DontInline function control, so that the inlining passes will inline them. SwiftShader will still have to modify their code to add this pass before the other passes are run.
