Two new matchers for `CXXNewExpr` are added which may be useful e.g. in
`clang-tidy` checkers. One of them is `isArray` which matches `new[]` but not
plain `new`. The other one, `hasArraySize` matches `new[]` for a given size.
llvm-svn: 318909
Summary:
This allows `linkageSpecDecl` to be used from `clang-query`.
See also D31869 which similary adds `isStaticStorageClass`.

Summary:
This allows the clang-query tool to use matchers like
"integerLiteral(equals(32))". For this to work, an overloaded function
is added for each possible parameter type.

Summary:
This adds a new ASTMatcher for CXXStdInitializerListExprs that matches C++ initializer list expressions.
The primary motivation is to use it to fix [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]] (review here [[ https://reviews.llvm.org/D32767 | D32767 ]]).

Summary:
I needed to know whether a FieldDecl had an in-class
initializer for D26453. I used a narrowing matcher there, but a
traversal matcher might be generally useful.

Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).

While this may seem like a lot of unrelated changes, they all relate back to fixing HasDeclarationMatcher.
This now allows us to write a matcher like:
varDecl(hasType(namedDecl(hasName("Foo"))))
that matches code using typedefs, objc interfaces, template type parameters, injected class names, or unresolved using typenames.

It's better not to rely on the diagnostics engine to pretty print the

Change to original: ifndef out tests in Windows due to /-separated

Summary:
Often one is only interested in matches within the main-file or matches
that are not within a system-header, for which this patch adds
isInMainFile and isInSystemFile. They take no arguments and narrow down
the matches.
The isInFileMatchingName is mainly thought for interactive
clang-query-sessions, to make a matcher more specific without restarting
the session with the files you are interested in for that moment. It
takes a string that will be used as regular-expression to match the
filename of where the matched node is expanded.

There was an assumption that there were no matchers that were overloaded
