Douglas Gregor 9d73cabf22 Template instantiation for "if" statements. Also:
- Skip semantic analysis of the "if" condition if it is type-dependent.
  - Added the location of the "else" keyword into IfStmt, so that we can
    provide it for type-checking after template instantiation.

Douglas Gregor d9034f0b89 In C++, warn when something previously declared as a "struct" is later
declared as a "class", or vice-versa. This warning is under the
control of -Wmismatched-tags, which is off by default.

Anders Carlsson f2a2e338ff Add return type checking for overriding virtual functions. We currently don't check covariance but that's next.

Douglas Gregor 2ec748cd5a Implement explicit instantiations of member classes of class templates, e.g.,
template<typename T>
  struct X {
    struct Inner;
  };

  template struct X<int>::Inner;

This change is larger than it looks because it also fixes some
a problem with nested-name-specifiers and tags. We weren't requiring
the DeclContext associated with the scope specifier of a tag to be
complete. Therefore, when looking for something like "struct
X<int>::Inner", we weren't instantiating X<int>. 

This, naturally, uncovered a problem with member pointers, where we
were requiring the left-hand side of a member pointer access
expression (e.g., x->*) to be a complete type. However, this is wrong:
the semantics of this expression does not require a complete type (EDG
agrees).

Stuart vouched for me. Blame him.

Ted Kremenek 3b204e4c2e Add some basic type checking for attributes ns_returns_retained and
cf_returns_retained. Currently this attribute can now be applied to any
Objective-C method or C function that returns a pointer or Objective-C object
type.

Modify the tablegen definition of diagnostic 'warn_attribute_wrong_decl_type' to
expect that the diagnostics infrastructure will add quotes around the attribute
name when appropriate. Alonq with this change, I modified the places where this
warning is issued to passed the attribute's IdentifierInfo* instead of having a
hard-coded C constant string.

Douglas Gregor bbbb02d463 Explicit instantiations of templates now instantiate the definitions
of class members (recursively). Only member classes are actually
instantiated; the instantiation logic for member functions and
variables are just stubs.

Douglas Gregor f61eca93c0 Improve the semantic checking for explicit instantiations of
templates. In particular:
  - An explicit instantiation can follow an implicit instantiation (we
  were improperly diagnosing this as an error, previously).
  - In C++0x, an explicit instantiation that follows an explicit
  specialization of the same template specialization is ignored. In
  C++98, we just emit an extension warning.
  - In C++0x, an explicit instantiation must be in a namespace
  enclosing the original template. C++98 has no such requirement.

Also, fixed a longstanding FIXME regarding the integral type that is
used for the size of a constant array type when it is being instantiated.

probably be rethought, I'll file a bugzilla.

Chris Lattner 851eb927d7 Fix rdar://6881069, a crash on a form of vector_size that we
don't support.  While it would be nice to support this eventually,
this form is not common at all (just seen in gcc testsuite) and
it might be better to model vector_size as a type attribute anyway.
For now just emit a nice error on it.

Douglas Gregor d002c7bc58 Encapsulate template arguments lists in a new class,
TemplateArgumentList. This avoids the need to pass around
pointer/length pairs of template arguments lists, and will eventually
make it easier to introduce member templates and variadic templates.

specialization" within a C++ template, and permit name lookup into the
current instantiation. For example, given:

  template<typename T, typename U>
  struct X {
    typedef T type;

    X* x1;  // current instantiation
    X<T, U> *x2; // current instantiation
    X<U, T> *x3; // not current instantiation
    ::X<type, U> *x4; // current instantiation
    X<typename X<type, U>::type, U>: *x5; // current instantiation

Douglas Gregor e362cea568 Implement the semantics of the injected-class-name within a class
template. The injected-class-name is either a type or a template,
depending on whether a '<' follows it. As a type, the
injected-class-name's template argument list contains its template
parameters in declaration order.

As part of this, add logic for canonicalizing declarations, and be
sure to canonicalize declarations used in template names and template
arguments. 

A TagType is dependent if the declaration it references is dependent.

I'm not happy about the rather complicated protocol needed to use
ASTContext::getTemplateSpecializationType.
