Summary:
This revision adds three new Stencil combinators:
* `expression`, which idiomatically constructs the source for an expression,
including wrapping the expression's source in parentheses if needed.
* `deref`, which constructs an idiomatic dereferencing expression.
* `addressOf`, which constructs an idiomatic address-taking expression.

Summary:
This revision adds `run`, a StencilPart that runs a user-defined function that
computes a result over `MatchFinder::MatchResult`.

Summary:
This revision add the `access` and `ifBound` combinators to the Stencil library:
* `access` -- constructs an idiomatic expression for accessing a member (a
`MemberExpr`).
* `ifBound` -- chooses between two `StencilParts` based on the whether an id is
bound in the match (corresponds to the combinator of the same name in
RangeSelector).

Add support for creating a `StencilPart` from any `RangeSelector`, which
broadens the scope of `Stencil`.
Correspondingly, deprecate Stencil's specialized combinators `node` and `sNode`
in favor of using the new `selection` combinator directly (with the appropriate
range selector).

Summary: This fixes a few places in the Stencil implementation where a unique_ptr is created at a callsite that expects shared_ptr. Since the former implicitly converts to the latter, the code compiles and runs correctly as is. But, there's no reason to involve unique_ptr -- the current code was leftover from a previous version in which unique_ptr was the expected type.

Summary:
This file defines the *Stencil* abstraction: a code-generating object, parameterized by named references to (bound) AST nodes. Given a match result, a stencil can be evaluated to a string of source code.
A stencil is similar in spirit to a format string: it is composed of a series of raw text strings, references to nodes (the parameters) and helper code-generation operations.
See thread on cfe-dev list with subject "[RFC] Easier source-to-source transformations with clang tooling" for background.
