This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.

Intorduces an abstraction for DynTypedNode which makes
is impossible to create in ways that introduced the bug;
also hides the implementation details of the template
magic away from the user and prepares the code for adding
QualType and TypeLoc bindings, as well as using DynTypedNode
instead of overloads for child and ancestor matching.
getNodeAs<T> was changed towards a non-pointer type, as
we'll want QualType and TypeLoc nodes to be returned
by value (the alternative would be to create new storage
which is prohibitively costly if we want to use it for
child / ancestor matching).
DynTypedNode is moved into a new header ASTTypeTraits.h,
as it is completely independent of the rest of the matcher
infrastructure - if the need comes up, we can move it to
a more common place.
The interface for users before the introduction of the
common storage change remains the same, minus the introduced
bug, for which a regression test was added.

isWritten() returns false, if shouldVisitImplicitCode() returns true.
Previously those CXXCtorInitializers were always skipped.
In order to make this change easier to test, this patch also extends the
test class template ExpectedLocationVisitor to support arbitrary numbers
of expected matches and disallowed matches.

ASTMatchers have the same name as the corresponding AST nodes
but are lower case. The only exceptions are the "CXX" prefixes
which are not copied over to the matcher names as the goal is to
actually remove these prefixes from the AST node names.

name. This should reduce the amount of warning false positives about bad HTML
in comments when the comment author intended to put a reference to a template.
This change will also enable us parse the comment as intended in these cases.
Fixes part 1 of PR13374.

Add a flag PrintingPolicy::DontRecurseInDeclContext to provide "terse" output
from DeclPrinter. The motivation is to use DeclPrinter to print declarations
in user-friendly format, without overwhelming user with inner detail of the
declaration being printed.
Also add many tests for DeclPrinter. There are quite a few things that we
print incorrectly: search for WRONG in DeclPrinterTest.cpp -- and these tests
check our output against incorrect output, so that we can fix/refactor/rewrite
the DeclPrinter later.

The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this
breaks libclang binary compatibility, but should not be a problem since API is
so new.
This also fixes PR13372 as a side-effect.

Now internal representation of plain text in comment AST does not contain
character references, but the characters themselves.

and became necessary with the change to require BindableMatchers
for binding.
Also fixes PR 13445: "hasSourceExpression only works for implicit casts".

as per Chandler's request:
- introduces a new matcher base type BindableMatcher that
provides the bind() call
- makes all dynamic-cast matcher creation functions return
BindableMatchers; the special case about dynamic-cast
matchers is that the node they match on and the node
their child matchers match on are the same node, just
casted to a different type; thus, there is no ambiguity
on what bind() matches on; additionally, those are the
matchers that we name with nouns in the matcher language,
so it's easy for users to intuitively know which matchers
are bindable
To make this change possible, we got rid of a non-orthogonal
implementation of thisPointerType, which had an implicit
dynamic-cast matcher from CallExpr to CXXMemberCallExpr; as
alternative, we now provide a memberCall dynamic-cast matcher
and thisPointerType is a predicate on CXXMemberCallExpr.
Last, the ArgumentAdaptingMatcher is actually not required
for the implementation of makeDynCastAllOfComposite - this
simplification makes it more obvious where the bind() call
can be used based on the matcher creation function types.

The assertion was wrong in case we have a verbatim block without a closing
command.
Also add tests for closing command name in a verbatim block, since now it can
be empty in such cases.
