[test] Simplify coro-inline.ll

[aeubanks]

Summary

The debug info metadata is unnecessary.
Instead of trying to replicate the -O0 pipeline, just call it.
Use -passes instead of -enable-new-pm.
Remove some unnecessary attributes.

This makes the test pass when -enable-new-pm is on by default.

if removing debug info, sample profile might not be found function(@ff) that should be inlined in SampleProfileLoader
