Re: [PATCH v13 0/7] MR450: vkd3d-shader/ir: Flatten structured control flow instructions.

[Conor McCarthy (＠cmccarthy)]

How about we add an assert-like helper function which does nothing if not specifically enabled in the build. It can emit the source name and line number similar to `vkd3d_unreachable()`. We can use it internally on tests and shader collections. I've been adding asserts to document intended constraints and verify they hold broadly, but I think release builds shouldn't do that.
