5.10 cherry-pick of #68550

  • Explanation: Fixes a use-after-free in SourceKit diagnostic logic
  • Scope: Affects SourceKit diagnostics
  • Issue: rdar://111589090
  • Risk: Low, the fix is small and straightforward
  • Testing: Passes the test suite
  • Reviewer: Ben Barham

As noted by the comment, storing a `StringRef` is
indeed brittle. Update to use a StringMap.

Switch to storing the necessary edit information
instead.
