Move (llvm-original-di-preservation) test example output into the Inputs...

Move (llvm-original-di-preservation) test example output into the Inputs directory (since it's an input to the test execution)

The "Inputs" subdirectory is used for all files read by the test, not
only those used as input to the execution - so even though this file is
used as a golden reference for the output of the test, it's still an
input to the test execution (it is read in the process of executing the
test).
