I have the totally opposite experience: I can't do any debugging efficiently 
without this option.  Empirically, most new-comers to writing tests with 
FileCheck (in MLIR, TensorFlow, XLA, IREE, etc.) have been manually adding 
-dump-input-on-failure hard-coded into the test themselves, which is a pretty 
good indication.

Having something contextual around the failures would work for me as well: but 
the previous situation was just not usable for me.
