John McCall 91f1a02648 Typedefs can be redeclared. That seems like something we should record in
the AST lest we run into some crazy canonicalization bug like PR5874.

Eli Friedman 84341cd668 Make sure to explicitly pass type/value dependence to Expr constructor. This
caught several cases where we were not doing the right thing. I'm
not completely sure all cases are being handled correctly, but this should
be an improvement.

Chandler Carruth 585fb1e97e Fix support for const_cast<>s of array types which actual change the
CV-qualifiers. Remove an error expectation from the 'good' set of const-cast
test cases. With this patch, the final non-template test case from PR5542
passes. (It's the same as the one already in const-cast.cpp.)

Chandler Carruth 607f38e05f Correctly refer to element CVR qualifications when determining if a type is
more or less cv-qualified than another during implicit conversion and overload
resolution ([basic.type.qualifier] p5). Factors the logic out of template
deduction and into the ASTContext so it can be shared.

This fixes several aspects of PR5542, but not all of them.

Chandler Carruth c25c6ee3db Handle using declarations in overloaded and template functions during ADL and
address resolution. This fixes PR5751.

Also, while we're here, remove logic from ADL which mistakenly included the
definition namespaces of overloaded and/or templated functions whose name or
address is used as an argument.

David Chisnall 3a509cd8cc Fix for bug 5691.
This fixes throwing exceptions inside @catch blocks nested inside outer @try blocks and also fixes jumping from an inner @finally to an outer @finally (via any relevant @catch blocks).

The code exhibiting this bug was based on code from CGObjCMac.  I believe that this bug may still be present on the Mac runtimes, although the test case in the bug contains a few GNUisms and won't compile without some minor tweaks with Apple's libobjc.

Douglas Gregor 25ab25f39d When using a default function argument for a function template (or
member function thereof), perform the template instantiation each time
the default argument is needed. This ensures that
  (1) We get different CXXTemporary objects for each instantiation, and
  (2) Any other instantiations or definitions triggered by the
  instantiation of the default argument expression are guaranteed to
  happen; previously, they might have been suppressed, e.g., because
  they happened in an unevaluated context.

This fixes the majority of PR5810. However, it does not address the
problem where we may have multiple uses of the same CXXTemporary
within an expression when the temporary came from a non-instantiated
default argument expression.

John McCall 1c7e6ec27b Don't inject the class name until that magical lbrace.
Because of the rules of base-class lookup* and the restrictions on typedefs, it

spurious acceptance of
  template <class T> class A : B<A> { ... };
instead of
  template <class T> class A : B<A<T> > { ... };

is well worth making another Parser->Sema call for.

John McCall c3f09ad253 Look through using decls when checking whether a name is an acceptable
nested-name specifier name.

fortunately, that refactor was inspired by having debugged this problem already,
so I can fix the bug quick (though probably not fast enough for the buildbots).

John McCall ea305edd63 Pull Sema::isAcceptableLookupResult into SemaLookup. Extract the criteria into
different functions and pick the function at lookup initialization time.
In theory we could actually divide the criteria functions into N different
functions for the N cases, but it's so not worth it.

Among other things, lets us invoke LookupQualifiedName without recomputing
IDNS info every time.

Do some refactoring in SemaDecl to avoid an awkward special case in LQN
that was only necessary for redeclaration testing for anonymous structs/unions ---
which could be done more efficiently with a scoped lookup anyway.

Douglas Gregor e1314a64b8 Switch the initialization required by return statements over to the
new InitializationSequence. This fixes some bugs (e.g., PR5808),
changed some diagnostics, and caused more churn than expected. What's
new:

  - InitializationSequence now has a "C conversion sequence" category
    and step kind, which falls back to
  - Changed the diagnostics for returns to always have the result type
    of the function first and the type of the expression second.
    CheckSingleAssignmentConstraints to peform checking in C. 
  - Improved ASTs for initialization of return values. The ASTs now
    capture all of the temporaries we need to create, but
    intentionally do not bind the tempoary that is actually returned,
    so that it won't get destroyed twice.
  - Make sure to perform an (elidable!) copy of the class object that
    is returned from a class.
  - Fix copy elision in CodeGen to properly see through the
    subexpressions that occur with elidable copies.
  - Give "new" its own entity kind; as with return values and thrown
    objects, we don't bind the expression so we don't call a
    destructor for it.

Note that, with this patch, I've broken returning move-only types in
C++0x. We'll fix it later, when we tackle NRVO.
