Nicolas Vasilache cab671d166 Lower affine control flow to std control flow to LLVM dialect 
This CL splits the lowering of affine to LLVM into 2 parts:
1. affine -> std
2. std -> LLVM

The conversions mostly consists of splitting concerns between the affine and non-affine worlds from existing conversions.
Short-circuiting of affine `if` conditions was never tested or exercised and is removed in the process, it can be reintroduced later if needed.

LoopParametricTiling.cpp is updated to reflect the newly added ForOp::build.

Stephan Herhut e8b21a75f8 Add an mlir-cuda-runner tool. 
This tool allows to execute MLIR IR snippets written in the GPU dialect
on a CUDA capable GPU. For this to work, a working CUDA install is required
and the build has to be configured with MLIR_CUDA_RUNNER_ENABLED set to 1.
