Some image ops return three or five dwords. Previously, we modeled that with a 4 or 8 dword register class. The register allocator could cleverly spot that some subregs were dead and allocate something else there, but that caused the de-optimization that waitcnt insertion would think that the result was used immediately. This commit allows such an image op to have a result with a three or five dword result, avoiding the above de-optimization.
