Tobias Grosser 79a947c233 GPGPU: Add basic support for kernel launches

Tobias Grosser 5779359624 GPGPU: Load GPU kernels
We embed the PTX code into the host IR as a global variable and compile it
at run-time into a GPU kernel.

Tobias Grosser 13c78e4d51 GPGPU: Emit data-transfer code
Also factor out getArraySize() to avoid code dupliciation and reorder some
function arguments to indicate the direction into which data is transferred.

Tobias Grosser 7287aeddf1 GPGPU: Complete code to allocate and free device arrays
At the beginning of each SCoP, we allocate device arrays for all arrays
used on the GPU and we free such arrays after the SCoP has been executed.

Tobias Grosser a71eedd4c5 GPURuntime: Drop polly_cleanupGPGPUResources
This function is currently unused and won't be used in this form again. Instead
of freeing many unrelated items at the same time, we will instead explicitly
call free function from the host-IR we generate for each object we want to free.
These specific free functions will be added together with the corresponding
host-IR generation code.

Tobias Grosser fa7b080218 GPGPU: initialize GPU context and simplify the corresponding GPURuntime interface.
There is no need to expose the selected device at the moment. We also pass back
pointers as return values, as this simplifies the interface.

Tobias Grosser 92713bea42 GPURuntime: Drop timing functionality
This functionality won't be used in the current iteration. Drop it for now to
reduce the surface of the library. We can always add it back in when we need
it again.

Tobias Grosser 856e31bb9c GPURuntime: Drop polly_allocateMemoryForHostAndDevice
There is function is currently unused and will be replaced in the future by
functions that allow to allocate memory only on the host or only on the device.

Tobias Grosser e602a07662 Reformat with clang-format
clang-format become way more stable. This time we mainly reformat function
signatures.

Tobias Grosser 4d96c8d714 clang-format: Many more files
After this commit, polly is clang-format clean. This can be tested with
'ninja polly-check-format'. Updates to clang-format may change this, but the
differences will hopefully be both small and general improvements to the
formatting.

We currently have some not very nice formatting for a couple of items, DEBUG()
stmts for example. I believe the benefit of being clang-format clean outweights
the not perfect layout of this code.
