Tobias Grosser 6217e18a7d Add preliminary implementation for GPGPU code generation.
Translate the selected parallel loop body into a ptx string and run it with the
cuda driver API. We limit this preliminary implementation to target the
following special test cases:

  - Support only 2-dimensional parallel loops with or without only one innermost
    non-parallel loop.
  - Support write memory access to only one array in a SCoP.

The patch was committed with smaller changes to the build system:

There is now a flag to enable gpu code generation explictly. This was required
as we need the llvm.codegen() patch applied on the llvm sources, to compile this
feature correctly. Also, enabling gpu code generation does not require cuda.
This requirement was removed to allow 'make polly-test' runs, even without an
installed cuda runtime.

Tobias Grosser 5a2925c6a1 cmake: Fix building of Polly on Apple system
The Apple linker fails by default, if some function calls can not be resolved at
link time. However, all functions that are part of LLVM itself will not be
linked into Polly, but will be provided by the compiler that Polly is loaded
into.  Hence, during linking we need to ignore failures due to unresolved
function calls.

Tobias Grosser 88aeaf6ac4 Detect the cuda library available.
We will use the cuda library for the upcoming automatic GPGPU code generation.

instead of loading the "LLVMConfig.cmake" which is only installed when

Tobias Grosser 080307119e Buildsystem: Add -no-rtti
Build Polly without run time type info (rtti), as otherwise Polly cannot be
loaded into a LLVM that is built without rtti.
