The current state of the top level Analysis/ directory is that it contains two libraries; a generic Analysis library (free from dialect dependencies), and a LoopAnalysis library that contains various analysis utilities that originated from Affine loop transformations. This commit moves the LoopAnalysis to the more appropriate home of `Dialect/Affine/Analysis/`, given the use and intention of the majority of the code within it. After the move, if there are generic utilities that would fit better in the top-level Analysis/ directory, we can move them. Differential Revision: https://reviews.llvm.org/D117351
