statement naming

- A recent ppcg/isl update caused the grid/block size upper bounds to
deviate by one from the oracle. This is not an effect that's visible at
runtime.
- Statement naming changed in polly. Update the testcases.

Kernel argument sizes now only get appended to the kernel launch parameter list if the OpenCL runtime is selected, not if CUDA runtime is chosen.

This commit *WILL COMPILE*.

1. `PPCG` now uses `isl_multi_pw_aff` instead of an array of `pw_aff`.
   This needs us to adjust how we index array bounds and how we construct
   array bounds.

2. `PPCG` introduces two new kinds of nodes: `init_device` and `clear_device`.
   We should investigate what the correct way to handle these are.

3. `PPCG` has gotten smarter with its use of live range reordering, so some of
   the tests have a qualitative improvement.

4. `PPCG` changed its output style, so many test cases need to be updated to
   fit the new style for `polly-acc-dump-code` checks.

Summary: PPCGCodeGeneration now attaches the size of the kernel launch parameters at the end of the parameter list. For the existing CUDA Runtime, this gets ignored, but the OpenCL Runtime knows to check for kernel-argument size at the end of the parameter list. (The resulting parameters list is twice as long. This has been accounted for in the corresponding test cases).
