Summary: Use the expanded features of the TableGen generic tables to avoid manually adding the combinatorially exploded set of intrinsics. The getAMDGPUImageDimIntrinsic lookup function is early-out, i.e. non-AMDGPU intrinsics will never look at the underlying table. Use a generic approach for getting the new intrinsic overload to keep the code simple, and make the image dmask handling more generic: - handle non-sampler image loads - handle the case where the set of demanded elements is not a prefix There is some overlap between this code and an optimization that happens in the backend during code generation. They currently complement each other: - only the codegen optimization can generate vec3 loads - only the InstCombine optimization can handle D16 The InstCombine optimization also likely covers more cases since the codegen optimization is fairly ad-hoc. Ideally, we'll remove the optimization in codegen once the infrastructure for vec3 is in place (which will probably take a long time). Modify the test cases to use dimension-aware intrinsics. This makes it easier to see that the test coverage for the new intrinsics is equivalent, and the old style intrinsics will be removed in a follow-up commit anyway.
