6.2 cherry-pick of #81414

  • Explanation: Fixes a SourceKit crash that could occur with -module-alias
  • Scope: Affects -module-alias with SourceKit
  • Issue: rdar://148130166
  • Risk: Low, the fix is straightforward
  • Testing: Added tests to test suite
  • Reviewer: Artem Chikin, Ben Barham

Previously we would insert StringRefs that reference the keys in the
map, but that breaks if the invocation ever gets copied. Switch to
`std::string`.
