  Log Message:
  -----------
  [libTooling] Add assorted `EditGenerator` combinators.

Summary:
This patch adds various combinators that help in constructing `EditGenerator`s:
   * `noEdits`
   * `ifBound`, specialized to `ASTEdit`
   * `flatten` and `flattenVector` which allow for easy construction from a set
     of sub edits.
   * `shrinkTo`, which generates edits to shrink a given range to another that
     it encloses.
