Would it make sense to have a default-off/experimental flag to enable this
to be actual code generation rather than comments & use that flag for
testing?
& I'm still not sure, even if it can't be done as anything other than
comments right now, whether a full golden-file style test for every piece
of the output is the best choice here (since a lot of the debug info output
is already well tested elsewhere - it seems like this extra testing here
would make this test brittle - when it could use FileCheck more sparsely to
test only particular features that are relevant to this test/to the
NVIDIA-specific handling/defaults?)?
