In order to deal with dynamic shapes occurs when compiling a object detection model like Faster Rcnn, many operators need shape functions for ManifestAlloc pass.

Several shape functions have been created or registered:

  1. floor
  2. log
  3. crop_and_resize
  4. mirror_pad

Register the shape function for `floor` operator. Otherwise, a bug will happen when input of floor is any.

Could you add test cases for crop_and_resize and mirror_pad in tests/python/relay/test_any.py?

@icemelon9 I have added test case for crop_and_resize and mirror_pad in tests/python/relay/test_any.py.

And there is something I may need to illustrate further. According to the MirrorPadRel function, mirror_pad only accepts static input shape. However, mirror_pad and another operator with dynamic input shape may get fused into a same function, and then the shape function of 'mirror_pad' is necessary.
