To reproduce:
```
using AMDGPU, Enzyme, Test

dir = tempname(); mkdir(dir)

begin
function cos_kernel(A)
i = workitemIdx().x
if i <= length(A)
A[i] = cos(A[i])
end
return nothing
end

function grad_cos_kernel(A, dA)
autodiff_deferred(Reverse, Const(cos_kernel), Const, Duplicated(A, dA))
return nothing
end

let
A = AMDGPU.ones(64,)
@roc groupsize=length(A) cos_kernel(A)
A = AMDGPU.ones(64,)
dA = similar(A)
dA .= 1
GPUCompiler.@device_code dir=dir @roc groupsize=length(A) grad_cos_kernel(A, dA)
end
end
```
Error: `HIPError(code hipErrorNoBinaryForGpu, no binary for GPU)`
