Throw a runtime error if tape size mismatch is detected

[vchuravy]

On #500 we now get a reasonable error. @wsmoses it looks we can't emit branches in the allocator? That would be required to not make this hurt performance.

ERROR: LoadError: Enzyme: Allocation failed, size mismatch between Julia 8 and Enzyme 98304 for Enzyme.Compiler.EnzymeTape{1024, NamedTuple{(Symbol("1"), Symbol("2"), Symbol("3")), Tuple{NamedTuple{(Symbol("1"), Symbol("2"), Symbol("3"), Symbol("4"), Symbol("5")), Tuple{NamedTuple{(Symbol("1"), Symbol("2"), Symbol("3"), Symbol("4"), Symbol("5"), Symbol("6"), Symbol("7")), Tuple{Core.LLVMPtr{Float32, 0}, Core.LLVMPtr{Float32, 0}, UInt64, UInt8, UInt32, Core.LLVMPtr{Float32, 0}, Core.LLVMPtr{Float32, 0}}}, Any, Any, UInt64, Bool}}, Any, Any}}}

This call needs to (in appropriate order) added to the returned list of added instructions

[vchuravy]

julia> sizeof(A{N, NT})
65568

julia> N = 684
684

julia> sizeof(A{N, NT})
8

So when we go over ~2^16 bytes we hit an internal threshold and we no longer allocate the NTuple as a chunk.
