Add support for "polymorphic" types to YAMLIO.
PolymorphicTraits can dynamically switch between other traits (Scalar, Map, or
Sequence). When inputting, the PolymorphicTraits type is told which type to
become, and when outputting the PolymorphicTraits type is asked which type it
currently is.
Also add support for TaggedScalarTraits to allow dynamically differentiating
between multiple scalar types using YAML tags.
Serialize empty maps as "{}" and empty sequences as "[]", so that types
are preserved when round-tripping PolymorphicTraits. This change has
equivalent semantics, but may break e.g. tests which compare output
verbatim.

This commit changes the way that the refactoring operation classes are
structured:
- Users have to call `initiate` instead of constructing an instance of the
class. The `initiate` is now supposed to have custom initiation logic, and
you don't need to subclass the builtin requirements.
- A new `describe` function returns a structure with the id, title and the
description of the refactoring operation.
The refactoring action classes are now placed into one common place in
RefactoringActions.cpp instead of being separate.

This commit allows the refactoring library to use its own set of
refactoring-specific diagnostics to reports things like initiation errors.

This commit simplifies the interface for the refactoring action rules and the
refactoring requirements. It merges the selection constraints and the selection
requirements into one class. The refactoring actions rules must now be
implemented using subclassing instead of raw function / lambda pointers. This
change also removes a bunch of template-based traits and other
template definitions that are now redundant.

local-rename action
This commit introduces the clang-refactor tool alongside the local-rename action
which uses the existing renaming engine used by clang-rename. The tool
doesn't actually perform the source transformations yet, it just provides
testing support. This commit also moves only one test from clang-rename over to
test/Refactor. I will continue to move the other tests throughout
development of clang-refactor.
The following options are supported by clang-refactor:
-v: use verbose output
-selection: The source range that corresponds to the portion of the source
that's selected (currently only special command test:<file> is supported).
Please note that a follow-up commit will migrate clang-refactor to
libTooling's common option parser, so clang-refactor will be able to use
the common interface with compilation database and options like -p, -extra-arg,
etc.
The testing support provided by clang-refactor is described below:
When -selection=test:<file> is given, clang-refactor will parse the selection
commands from that file. The selection commands are grouped and the specified
refactoring action invoked by the tool. Each command in a group is expected to
produce an identical result. The precise syntax for the selection commands is
described in a comment in TestSupport.h.

rule classes
This commit changes the way that the refactoring results are produced. Instead
of using different `RefactoringActionRule` subclasses for each result type,
Clang now use a single `RefactoringResultConsumer`. This was suggested by
Manuel in https://reviews.llvm.org/D36075.

This patch implements the initial support for refactoring action rules. The
first rule that's supported is a "source change" rule that returns a set of
atomic changes. This patch is based on the ideas presented in my RFC:
http://lists.llvm.org/pipermail/cfe-dev/2017-July/054831.html
The following pieces from the RFC are added by this patch:
- `createRefactoringRule` (known as `apply` in the RFC)
- `requiredSelection` refactoring action rule requirement.
- `selection::SourceSelectionRange` selection constraint.
