implements quasiquotes

- Additions to the reflection API:

  - The Quasiquotes implicit class that defines `q`, `tq`, `pq` and `cq`
    interpolators which now become a part of the `scala.reflect.api.
    Universe`.

  - Implementations of the interpolators are macro-based
    and are hardwired through `FastTrack`.

  - The `Liftable` class and the `StandardLiftables` slice of the cake
    that provide a type class and a bunch of its instances that allow
    to easily splice user-defined types into quasiquotes.

  - Additional methods in `BuildUtils` that are used by the quasiquote
    macro to generate trees, notably:

    - `SyntacticClassDef`. An extractor/constructor that allows to
      construct and deconstruct classes using arguments that mirror
      syntactic form of ClassDefs (e.g. constructor outside of the
      body).

    - `TupleN`, `TupleTypeN`. Extractor/constructor for easy
      construction of ast that represents a tuple term or type
      with given amount of elements.

- Actual implementation of quasiquotes in the `scala.tools.reflect.
  quasiquotes` package which is organized into a cake called
  `Quasiquotes` with slices introducing core abstractions necessary to
  splice into Scala syntax, routines for interfacing with the parser,
  and customized reifiers for tree construction and deconstruction.
