The generator for LibASTMatchersReference.html didn't get run last time
ASTMatchers changes were made. Here are up-to-date docs.

Added two new narrowing matchers:
* hasMethod: aplies a matcher to a CXXRecordDecl's methods until a match is made
  or there are no more methods.
* hasCanonicalType: applies a matcher to a QualType's canonicalType.

Enhanced hasOverloadedOperatorName to work on CXXMethodDecl as well as
CXXOperatorCallExpr.

Updated tests and docs.

Instead of passing NULL on to sub-matcher, just return false. Updated tests and
regenerated docs.

TemplateSpecializationType doesn't quite have getDecl(). Need to go
through TemplateName to get a TemplateDecl.

Added test cases for the hasDeclaration() overload for
TemplateSpecializationType. Also introduced the type matcher
templateSpecializationType() used by the new hasDeclaration() test case.

Updated LibASTMatchersReference.

Using a new metafunction for detecting the presence of the member
'getDecl' in a type T, added support to hasDeclaration for any such type
T. This allows hasDecl() to be replaced and enables several other
subclasses of clang::Type to use hasDeclaration.

Updated unittests and LibASTMatchersReference.html.

This is a powerful tool when doing iterative refined matches,
where another match is started inside the match callback of the first
one; this allows for example to find out whether the node was in
the condition or body of its parent if-statement.

This is in preparation for adding other overloaded matchers. This change
alone is a net win in LOC.
I went through all matchers and looked whether we could now encode them
as macro, or simplify them with the matcher atoms that were not
available before.

We found that findAll has been implemented incorrectly multiple times
by various people using the matchers. To prevent further wasted
development effort, it makes sense to add it as convenience matcher
implemented as eachOf(m, forEachDescendant(m)).

This patch also updates the docs with the new matchers.

We still need to make the python script understand some of the new
matchers, but this should be an improvement.

This allows linking to LibASTMatchersRefernce.html#<matcher><N>Anchor to
link to the N'the declaration of a matcher and automatically expand
its documentation.

of matchers, categorized by type and fully expanded for the
context in which they can be used.

I used a script to generate this documentation which I'll want
to be scrunitized by a code review before checking it in.
