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).
