Change how bump allocators are initialized Define 'cuda_global_ptr' in runtime library

The pairwise test has been flaky before, so this looks like it is working. I'm going to leave this open until I have some time to give it a proper look, which might be a while. |

Alright, thanks! I can't reproduce the pairwise test failure either. |

This PR allows
@cudacallers to pick a custom allocation function and implements a bump allocator, as per your request, @maleadt, in #419. I also threw in an example program that doubles as a test.
