1.11 error AssertionError: Base.isdispatchtuple

```julia
(f, tt, world, typeof(f)) = (Enzyme.Compiler.add_one_in_place, Tuple{Any}, 0x000000000000683a, typeof(Enzyme.Compiler.add_one_in_place))

Stacktrace:
[1] methodinstance
@ ~/.julia/packages/GPUCompiler/2CW9L/src/jlgen.jl:82 [inlined]

function nested_codegen!(mode::API.CDerivativeMode, mod::LLVM.Module, f, tt, world)
+ @show f, tt, world, typeof(f)
funcspec = GPUCompiler.methodinstance(typeof(f), tt, world)
nested_codegen!(mode, mod, funcspec, world)
end
```

So essentially here we request a generic form of the function `add_one_in_place` requesting it for an any input. This works on 1.10, but fails on 1.11 hitting the aforementioned assertion error

Start with GPUCompiler/2CW9L/src/jlgen.jl:82 and the nested_codegen! call to GPUCompiler.methodinstance shown in the report. Compare the Julia 1.10 and 1.11 behavior for Enzyme.Compiler.add_one_in_place with Tuple{Any}; done means the generic request no longer triggers the Base.isdispatchtuple assertion.
