  Log Message:
  -----------
  SourceManager: Factor out helpers for common SLocEntry lookup pattern, NFC

Add helpers `getSLocEntryOrNull`, which handles the `Invalid` logic
around `getSLocEntry`, and `getSLocEntryForFile`, which also checks for
`SLocEntry::isFile`, and use them to reduce repeated code.
