AMDGPU plugin doesn't use any implicitarg for COV4, but it does so for COV5. So, we are not keeping two separate structures for implicitargs of COV4 and COV5.
If we use sizeof then it will always return 256 corresponding to COV5 (even for cov4, which should be 56). That's why we need this function.
