Description

Pcard-72675

• Feature:
  Lots of files are directly placed in cinn/ir dir which does make cinn/ir dir a mess. This PR aims at improving structure of cinn/ir dir, enhancing its hierarchy.

• Details:

  1. Set cinn/ir/schedule dir, move all schedule relevant files into it;
  2. Set cinn/ir/test dir, move all unittestt files into it;
  3. Set cinn/ir/utils dir, move utility files that derived from ir_base.h, such as ir_printer.h, ir_mutator into it;
  4. Set cinn/ir/op dir, move ir_operators.h file that records most of operator-override into it.

• Result:
  By adopting this Pr, the structure of cinn/ir dir change from

  cinn/ir/
       ir_visitor.h
       ir_mutator.h
       ir_compare.h
       ir_operator.h

       ir_printer_test.cc
       ir_schedule.h
