Uses the new InsertPosition class (added in #94226) to simplify some of the IRBuilder interface, and removes the need to pass a BasicBlock alongside a BasicBlock::iterator, using the fact that we can now get the parent basic block from the iterator even if it points to the sentinel. This patch removes the BasicBlock argument from each constructor or call to setInsertPoint. This has no functional effect, but later on as we look to remove the `Instruction *InsertBefore` argument from instruction-creation (discussed [here](https://discourse.llvm.org/t/psa-instruction-constructors-changing-to-iterator-only-insertion/77845)), this will simplify the process by allowing us to deprecate the InsertPosition constructor directly and catch all the cases where we use instructions rather than iterators.
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.
