Even as the NPM has been in use by Polly for a while now, the majority of the tests continue using the LPM passes. This patch ports the tests to use the NPM passes (for example, by replacing a flag such as -polly-detect with -passes=polly-detect following the NPM syntax for specifying passes) with some exceptions for some missing features in the new passes. Relanding #90632.
Polly - Polyhedral optimizations for LLVM ----------------------------------------- http://polly.llvm.org/ Polly uses a mathematical representation, the polyhedral model, to represent and transform loops and other control flow structures. Using an abstract representation it is possible to reason about transformations in a more general way and to use highly optimized linear programming libraries to figure out the optimal loop structure. These transformations can be used to do constant propagation through arrays, remove dead loop iterations, optimize loops for cache locality, optimize arrays, apply advanced automatic parallelization, drive vectorization, or they can be used to do software pipelining.
