We generally do some clean up on test files so that they're easier to read and edit. Things like the `source_filename` and `datalayout` aren't really necessary, mangled names are more annoying to read than simple ones, and attributes and metadata that aren't necessary for the test can be removed. It's also nice to run things through `opt -instnamer` or manually name all of the SSA values so it's easier to edit in the future.
