segfault with julia master

[JeffBezanson]

Might be an issue with julia itself or GPUCompiler, but will post here for now:

julia> compile(fib, Tuple{Int}, "fib")

[vchuravy]

Fixed by https://github.com/JuliaGPU/GPUCompiler.jl/pull/324. So updating GPUCompiler to 0.16 should fix this

[brenhinkeller]

I can try to bump the compat bounds on GPUCompiler in my current PR and see if that has any unexpected consequences

[brenhinkeller]

Looks like we have some work to do: #76

Integration tests are actually passing on 1.8 though, meaning we are successfully compiling standalone executables with GPUCompiler 0.16 -- and I think I know the problem with integration tests on 1.9, so can probably get those up and running without too much trouble.
