[PATCH v2 0/4] MR568: vkd3d-shader: Miscellaneous changes in view of the CFG structurizer.
-- v2: vkd3d-shader: Make relative address sources mutable too. vkd3d-shader/spirv: Normalise the shader before allocating registers. tests: Test a couple of degenerate switch instances. tests: Add a test with non-trivial control flow. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/568
