Douglas Gregor 87f5406081 When implicitly declaring operators new, new[], delete, and delete[],
give them the appropriate exception specifications. This,
unfortunately, requires us to maintain and/or implicitly generate
handles to namespace "std" and the class "std::bad_alloc". However,
every other approach I've come up with was more hackish, and this
standard requirement itself is quite the hack.

Fixes PR4829.

Douglas Gregor e1d2ef3508 Refactor MarkDeductedTemplateParameters into
MarkUsedTemplateParameters, which is able to mark template parameters
used within non-deduced contexts as well as deduced contexts. Use this
to finish the implementation of [temp.deduct.partial]p11.

Douglas Gregor 406f634df5 Tighten up checking of non-dependent arguments as part of template
argument deduction. This fixes the new test case (since partial
ordering does not have a "verify the results of deduction" step), and
will allow failed template argument deductions to return more quickly
for, e.g., matching class template partial specializations.

Douglas Gregor c732aba9a9 Cleanup and test C++ default arguments. Improvements include:
- Diagnose attempts to add default arguments to templates (or member
    functions of templates) after the initial declaration (DR217).
  - Improve diagnostics when a default argument is redefined. Now, the
    note will always point at the place where the default argument was
    previously defined, rather than pointing to the most recent
    declaration of the function.

John McCall 1806c2795b Track a class template specialization's point of instantiation separately
from its location.  Initialize appropriately.

When implicitly creating a declaration of a class template specialization
after encountering the first reference to it, use the pattern class's
location instead of the location of the first reference.

John McCall e94dd7ccf5 When adding a friend class declaration to the lookup tables, use the access specifier
of any previous declaration in case we replace it in a class's declaration table.
Fixes bug 4858.  This sort of thing makes me reconsider putting friend declarations in
declaration lists.

John McCall 2dc078f24e Ensure that the tag decls of friend decls aren't added to the friending class's

John McCall aa74a0c3b5 Omnibus friend decl refactoring. Instead of cloning AST classes for friend
declarations of same, introduce a single AST class and add appropriate bits
(encoded in the namespace) for whether a decl is "real" or not.  Much hackery
about previously-declared / not-previously-declared, but it's essentially
mandated by the standard that friends alter lookup, and this is at least
fairly non-intrusive.

Refactor the Sema methods specific to friends for cleaner flow and less nesting.

Incidentally solve a few bugs, but I remain confident that we can put them back.

Douglas Gregor c190523d7a When a member reference expression includes a qualifier on the member
name, e.g.,
  
  x->Base::f()

retain the qualifier (and its source range information) in a new
subclass of MemberExpr called CXXQualifiedMemberExpr. Provide
construction, transformation, profiling, printing, etc., for this new
expression type.

When a virtual function is called via a qualified name, don't emit a
virtual call. Instead, call that function directly. Mike, could you
add a CodeGen test for this, too?

Douglas Gregor 053f691d5e Improve diagnostics and recovery when the nested-name-specifier of a
qualified name does not actually refer into a class/class
template/class template partial specialization. 

Improve printing of nested-name-specifiers to eliminate redudant
qualifiers. Also, make it possible to output a nested-name-specifier
through a DiagnosticBuilder, although there are relatively few places
that will use this leeway.

Chris Lattner d99bd52c73 Eli points out that we really must diagnose "void* > 0" as an extension.
Explicitly add it as an EXTENSION instead of an EXTWARN so that it only
comes out with -pedantic.  Thanks Eli!

destructors, and conversion functions of a class template partial
specialization.

John McCall d1e9d835f3 Argument-dependent lookup for friend declarations. Add a new decl type,
FriendFunctionDecl, and create instances as appropriate.

The design of FriendFunctionDecl is still somewhat up in the air;  you can
befriend arbitrary types of functions --- methods, constructors, etc. ---
and it's not clear that this representation captures that very well.
We'll have a better picture when we start consuming this data in access
control.

John McCall 93343b9466 Permit a class to friend its members in C++0x, without restriction.
Permit a class to friend its class members in C++ 98, as long as extensions
are enabled (and even when they aren't, only give an extwarn about it).

Douglas Gregor 15acfb9f50 When we encounter a dependent type that was parsed before we know that
we were going to enter into the scope of a class template or class
template partial specialization, rebuild that type so that it can
refer to members of the current instantiation, as in code like

  template<typename T>
  struct X {
    typedef T* pointer;
    pointer data();
  };

  template<typename T>
  typename X<T>::pointer X<T>::data() { ... }

Without rebuilding the return type of this out-of-line definition, the
canonical return type of the out-of-line definition (a TypenameType)
will not match the canonical return type of the declaration (the
canonical type of T*).
