We are working towards removing uses of Scop::getStmtFor(BB). In this patch, we remove dependency of Scop::getStmtFor(Inst) on getStmtFor(BB). To do so, we introduce a map of instructions to their corresponding scop statements and use it to get the instructions' statement.

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.
