Summary:
We would not perform substitution at an appropriate point, allowing strange
results to appear. We would accepts things that we shouldn't or mangle things incorrectly. Note that this hasn't fixed the other cases like
template-template parameters or non-type template parameters.

This was only used to ensure that the traversal order was the same as the
insertion order, but that guarantee was already being provided by the use
of a FoldingSetVector.

referenced as a member of the current instantiation. In that case, deduce the
type of the function to a dependent type rather than exposing an undeduced auto
type to the rest of the current instantiation.
The standard doesn't really say that the type is dependent in this case; I'll
bring this up with CWG.

When a local extern declaration redeclares some other entity, the type of that
entity is merged with the prior type if the prior declaration is visible (in C)
or is declared in the same scope (in C++).
- Make LookupRedeclarationWithLinkage actually work in C++, use it in the right
set of cases, and make it track whether it found a shadowed declaration.
- Track whether we found a declaration in the same scope (for C++) including
across serialization and template instantiation.

This change unifies the logic for template instantiation of methods and
functions declared with typedefs.
It ensures that SubstFunctionType() always fills the Params out param
with non-null ParmVarDecls or returns null.

If we friend a declaration twice, that should not make it visible to
name lookup in the surrounding context. Slightly rework how we handle
friend declarations to inherit the visibility of the prior
declaration, rather than setting a friend declaration to be visible
whenever there was a prior declaration.

This breaks the build of basic patterns with repeated friend
declarations. See the added test case in SemaCXX/friend.cpp or the test
case reported to the original commit log.

This replaces a long list of declarations for visitor functions with
a list generated from DeclNodes.inc. Nothing really interesting came
out of it; we had comprehensive coverage anyway
(excluding FriendTemplateDecls).

As noted by Richard in the post:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130624/082605.html, the following code should not add an entry
into PendingLocalImplicitInstantiations, since local instantiations
should only occur within the context of other instantiations:
int foo(double y) {
struct Lambda {
template<class T> T operator()(T t) const { return t; };
} lambda;
return lambda(y);
}
Hence the attached code does the following:
1) In MarkFunctionReferenced, check if ActiveInstantiations.size()
is non-zero before adding to PendingLocalImplicitInstantiations.
2) In InstantiateFunctionDefinition, we swap out/in
PendingLocalImplicitInstantiations so that only those
pending local instantiations that are added during the instantiation
of the current function are instantiated recursively.

instantiate the inherited constructor template and mark that as the constructor

We keep the "as written" storage class, but that is a fuzzy concept for
instantiations. With this patch instantiations of methods of class templates
now get a storage class that is based on the semantics of isStatic(). With this
can simplify isStatic() itself.

For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.
This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.
