Test Plan:
In addition to the test plan of D34696255 (https://github.com/pytorch/pytorch/commit/f2ca4341c9008472022227b43d943af3e5e46e81), ran the following for glow shape inference support:
`buck test glow/fb/torch_glow/tests/model_tests:basic_shape_tests -- ShapeInferenceTest.TestToLengthsToOffsets`
`servicelab create cogwheel_pyper_inference_fullsync_ads_inline_cvr_post_imp -a D35226685`

`servicelab create cogwheel_pyper_inference_fullsync_ads_10x_ctr_mbl_feed_non_mimo -a D35226685`

Model published: f335674524. Inference check job finished: f335693514.
Inference test tw tasks: https://fburl.com/tupperware/8pb3ep45.
I checked that replayer and storage tier task logs look good. Nnpi tier logs (https://fburl.com/tupperware/4grcwoil, P493812547) have various printouts related other longstanding operators missing shape inference inference support. I'll ask Oleg to sanity check these.
