[llvm] [NFCI][Coroutines] update tests to autogenerated formatting (PR #178358)

Some of these look clearly beneficial (e.g. up to coro-align8.ll) and some don't (e.g. coro-debug-coro-frame.ll). Some look like they are necessary to be able to test the behavior at all in the future (e.g. coro-byval-param.ll -- anything that relies on testing solely the frame struct will break once the gep type goes away).

I think this would be easier to review if the changes focused on the cases where the generated checks are fairly clearly beneficial and did not include cases where we're generating hundreds of check lines.

UTC has various options for cutting down the output to more relevant parts, but that needs case-by-case work.
