  Log Message:
  -----------
  [llvm][ADT] Overload output stream operator `<<` for `StringMapEntry` and `StringMap`.

Printing support enables the production of more useful error messages in unit testing e.g. when using matchers such as `UnorderedElementsAre()` to inspect the contents of a `StringMap`.
