Instead of having to change the API for tracking GPU memory, I suggest to
try a hack. Memory allocations use an alignement. For pymalloc, it's 8
bytes for example. On a GPU I expect at least 2 bytes or more likey
something much bigger like 16 bytes. For malloc, I also expect at least 2
bytes.

If it's the minimum is 2 bytes, good. Use the lowest bit as a "GPU" flag!
pointer|1.

Tracemalloc doesn't give access to pointers in its API, so it shouldn't
matter.
