Sean Silva be1971c4fc Rename tcp.abort_if to tcp.shape_observe_error ... This more clearly captures its semantics as a structural "observer" of code that we currently mark as NoSideEffect but eventually lowers to eager error handling code. Also, update LowerRankedShapes to erase it, now that the layering here is clear. That pass reifies the eager error handling code, so the need for the dummy op to keep things alive isn't needed. With this change, we are now ready to start lowering to LLVM! This is the current print-ir-after-all from e2e-lowering-pipeline: https://reviews.llvm.org/P8221		2020-05-18 13:38:47 -07:00
