[PATCH] D69625: [libTooling] Support implicit coercions in Stencil's `access` combinator.

Herald added a project: clang.
ymandel added a parent revision: D69613: [libTooling] Simplify type structure of `Stencil`s..

Changes `clang::transformer::access` to also support `RangeSelector` as the
second argument.  This change makes `access` consistent with `cat` in that it
will accept text, `RangeSelector` or `Stencil`. The plan is for all Stencil
arguments to be supported in this way to provide a uniform user experience for
Stencil arguments.
