From: Philip Oakley <philipoakley@iee.email>

To complement the `--stdin` and `--literally` test cases that verify that we can hash files larger than 4GB on 64-bit platforms using the LLP64 data model, here is a test case that exercises `hash-object` _without_ any options.

Just as before, we use the `big` file from the previous test case if it exists to save on setup time, otherwise generate it.
