Nathan Sidwell b2d0c16e91 [clang] p1099 using enum part 2
This implements the 'using enum maybe-qualified-enum-tag ;' part of
1099. It introduces a new 'UsingEnumDecl', subclassed from
'BaseUsingDecl'. Much of the diff is the boilerplate needed to get the
new class set up.

There is one case where we accept ill-formed, but I believe this is
merely an extended case of an existing bug, so consider it
orthogonal. AFAICT in class-scope the c++20 rule is that no 2 using
decls can bring in the same target decl ([namespace.udecl]/8). But we
already accept:

struct A { enum { a }; };
struct B : A { using A::a; };
struct C : B { using A::a;
using B::a; }; // same enumerator

this patch permits mixtures of 'using enum Bob;' and 'using Bob::member;' in the same way.

Artem Dergachev 6a079dfdc9 [ASTMatchers] Add forCallable(), a generalization of forFunction().
The new matcher additionally covers blocks and Objective-C methods.

This matcher actually makes sure that the statement truly belongs
to that declaration's body. forFunction() incorrectly reported that
a statement in a nested block belonged to the surrounding function.

forFunction() is now deprecated due to the above footgun, in favor of
forCallable(functionDecl()) when only functions need to be considered.

Stephen Kelly d6a06365cf [ASTMatchers] Fix matching after generic top-level matcher
With a matcher like

  expr(anyOf(integerLiteral(equals(42)), unless(expr())))

and code such as

  struct B {
    B(int);
  };

  B func1() { return 42; }

the top-level expr() would match each of the nodes which are not spelled
in the source and then ignore-traverse to match the integerLiteral node.
This would result in multiple results reported for the integerLiteral.

Fix that by only running matching logic on nodes which are not skipped
with the top-level matcher.

Tom Roeder 1844ab770c [ASTImporter] Add support for importing GenericSelectionExpr AST nodes.
This allows ASTs to be merged when they contain GenericSelectionExpr
nodes (this is _Generic from C11). This is needed, for example, for
CTU analysis of C code that makes use of _Generic, like the Linux
kernel.

The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter. Additionally, this change adds support for structural
equivalence of _Generic in the AST.

Stephen Kelly 246b428fb3 [AST] Ignore implicit nodes in IgnoreUnlessSpelledInSource mode
Update the ASTNodeTraverser to dump only nodes spelled in source.  There
are only a few which need to be handled, but Decl nodes for which
isImplicit() is true are handled together.

Update the RAV instances used in ASTMatchFinder to ignore the nodes too.
As with handling of template instantiations, it is necessary to allow
the RAV to process the implicit nodes because they need to be visitable
before the first traverse() matcher is encountered.  An exception to
this is in the MatchChildASTVisitor, because we sometimes wish to make a
node matchable but make its children not-matchable.  This is the case
for defaulted CXXMethodDecls for example.

Extend TransformerTests to illustrate the kinds of problems that can
arise when performing source code rewriting due to matching implicit
nodes.

This change accounts for handling nodes not spelled in source when using
direct matching of nodes, and when using the has() and hasDescendant()
matchers.  Other matchers such as
cxxRecordDecl(hasMethod(cxxMethodDecl())) still succeed for
compiler-generated methods for example after this change.  Updating the
implementations of hasMethod() and other matchers is for a follow-up
patch.
