The task was to write a pass that adds a call to the @trace_loop_iter_begin() and @trace_loop_iter_end() functions at the beginning and end of the loop.
Inside the module for affine.for, scf.for, scf.while @trace_loop_iter_begin() is inserted at the beginning of the loop body, @trace_loop_iter_end() is inserted before the yield operation. Nested loops of all supported types are processed. The @trace_loop_iter_begin and @trace_loop_iter_end. Functions are declared as private if they are not present in the module.
