Данный MLIR-пасс анализирует функции в модуле и вычисляет глубину вложенности циклов (scf.for, scf.while, affine.for) внутри каждой функции. Для каждого цикла рекурсивно вычисляется глубина вложенных регионов, представляющая уровень вложенности. Затем пасс сохраняет эти глубины циклов в виде атрибута-массива целых чисел под названием "my_loop_depths" на самой операции функции. Для вычисления глубины каждого региона цикла используется рекурсивная функция computeRegionDepth, которая возвращает максимальную глубину
