We should be using ANGLE's simulated vertex attribute code now, but it is failing this old test.

Per discussion with Justin: while the test is technically invalid (it's legal to not generate INVALID_OPERATION for the draw call), Apple's OpenGL driver doesn't support KHR_robustness or KHR_robust_buffer_access_behavior. Therefore it seems that ANGLE should be doing the index validation, discovering that the draw call is invalid, and generating an error. Justin: could you post the current results of the test on macOS here?

PASS: MAX_UINT index was unable to be simulated PASS: MAX_UINT index did not crash FAIL: Huge index did not fail validation PASS: Huge index did not crash
