In preparation for turning on opt's -enable-new-pm by default, this pins uses of passes via the legacy "opt -passname" with pass names beginning with "polly-" and "polyhedral-info" to the legacy PM. Many of these tests use -analyze, which isn't supported in the new PM. (This doesn't affect uses of "opt -passes=passname"). rL240766 accidentally removed `-polly-prepare` in phi_not_grouped_at_top.ll, and it also doesn't use the output of -analyze.

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.
