DynTypedNode and ASTNodeKind are implemented as part of the clang AST
library, which uses the main clang namespace. There doesn't seem to be a
need for this extra level of namespacing.
I left behind aliases in the ast_type_traits namespace for out of tree
clients of these APIs. To provide aliases for the enumerators, I used
this pattern:
namespace ast_type_traits {
constexpr TraversalKind TK_AsIs = ::clang::TK_AsIs;
}
I think the typedefs will be useful for migration, but we might be able
to drop these enumerator aliases.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This is similar to the LLVM change https://reviews.llvm.org/D46290.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Needed to support something like "floatLiteral(equals(1.0))". The
parser for floating point numbers is kept simple, so instead of ".1" you
have to use "0.1".

Summary:
Recognize boolean literals for future extensions ("equals(true)").
Note that a specific VariantValue constructor is added to resolve
ambiguity (like "Value = 5") between unsigned and bool.

Individual matchers might not be convertible to each other's kind, but
they might still all be convertible to the target kind.
All the callers already know the target kind, so just pass it down.

Summary:
Replace variadic operator function pointer with an enum value.
Hiding the implementation of the variadic matcher will allow to specialize them for the operation performed.
In particular, it will allow for a more efficient allOf() matcher.

Summary:
The generic variadic matcher is faster (one less virtual function call
per match) and doesn't require template instantiations which reduces
compile time and binary size.
Registry.cpp.o generates ~14% less symbols and compiles ~7.5% faster.
The change also speeds up our clang-tidy benchmark by ~2%.

Summary:
Refactor VariantMatcher::MatcherOps to reduce the amount of generated code.
- Make some code type agnostic and move it to the cpp file.
- Return a DynTypedMatcher instead of storing the object in MatcherOps.
This change reduces the number of symbols generated in Registry.cpp by
~19%, the object byte size by ~17% and the compilation time (in non-release mode) by ~20%.

- Passing a map of names to values to the parser.
- Update the Sema interface to include completion for matchers.

directly to Registry.

Summary:
Refactor DynTypedMatcher into a value type class, just like Matcher<T>.
This simplifies its usage and removes the virtual hierarchy from Matcher<T>.
It also enables planned changes to replace MatcherInteface<T>.
Too many instantiaions of this class hierarchy has been causing Registry.cpp.o to bloat in size and number of symbols.

- Added conversion routines and checks in Matcher<T> that take a DynTypedMatcher.
- Added type information on the error messages for the marshallers.
- Allows future work on Polymorphic/overloaded matchers. We should be
able to disambiguate at runtime and choose the appropriate overload.
llvm-svn: 184429
This library supports all the features of the compile-time based ASTMatcher
library, but allows the user to specify and construct the matchers at runtime.
It contains the following modules:
- A variant type, to be used by the matcher factory.
- A registry, where the matchers are indexed by name and have a factory method
with a generic signature.
- A simple matcher expression parser, that can be used to convert a matcher
expression string into actual matchers that can be used with the AST at
runtime.
Many features where omitted from this first revision to simplify this code
review. The main ideas are still represented in this change and it already has
support working use cases.
Things that are missing:
- Support for polymorphic matchers. These requires supporting code in the
registry, the marshallers and the variant type.
- Support for numbers, char and bool arguments to the matchers. This requires
supporting code in the parser and the variant type.
- A command line program putting everything together and providing an already
functional tool.
