The refactoring in swiftlang#68760 accidentally caused us to start parsing skipped function bodies if they have parameters, as the local discriminator request kicks parsing through `getBody()`. Cherry-pick part of 47ff956 which was never landed, ensuring we don't call `getBody` for a skipped function body. This is meant to be a minimal low-risk change that fixes the issue in question, restoring the behavior we had in 5.10. Fixing the parser skipping behavior for `#sourceLocation` will be done in a follow-up. We also ought to see if there's a better way we can enforce that skipped function bodies don't end up getting parsed, for now I've added a test. rdar://131726797

6.0 cherry-pick of #75421
#sourceLocation()would incorrectly be diagnosed with an error in a function body when emitting a module. More generally, this change also stops us from needlessly parsing function bodies when emitting modules.
