What about translating automatic locals to function scope pointers?
This will make handling of automatic locals and local pointer
arguments similar, which is desirable as they are just a way to
describe the same thing (I understand automatic locals as just a
simpler way to use local buffers than local arguments).
In fact, pocl converts automatic locals to implicit "extra" kernel
arguments and manages both cases the same way.
