Douglas Gregor 97fd6e24c4 Add support for calls to overloaded member functions. Things to note:
- Overloading has to cope with having both static and non-static
    member functions in the overload set.
  - The call may or may not have an implicit object argument,
    depending on the syntax (x.f() vs. f()) and the context (static
    vs. non-static member function).
  - We now generate MemberExprs for implicit member access expression.
  - We now cope with mutable whenever we're building MemberExprs.

Douglas Gregor 55ad91fecb Ultrasimplistic sketch for the parsing of C++ template-ids. This won't
become useful or correct until we (1) parse template arguments
correctly, (2) have some way to turn template-ids into types,
declarators, etc., and (3) have a real representation of templates.

Douglas Gregor 4d87df5853 Delay parsing of default arguments of member functions until the class
is completely defined (C++ [class.mem]p2).

Reverse the order in which we process the definitions of member
functions specified inline. This way, we'll get diagnostics in the
order in which the member functions were declared in the class.

Douglas Gregor ad590506a7 Diagnose erroneous uses of out-of-line member definitions and scope
specifiers. Specifically: 
  * Determine when an out-of-line function definition does not match
    any declaration within the class or namespace (including coping
    with overloaded functions).
  * Complain about typedefs and parameters that have scope specifiers.
  * Complain about out-of-line declarations that aren't also
  definitions.
  * Complain about non-static data members being declared out-of-line.
  * Allow cv-qualifiers on out-of-line member function definitions.

Douglas Gregor 1349b457ee Place constructors and destructors into the DeclContext of the class,
just like all other members, and remove the special variables in
CXXRecordDecl to store them. This eliminates a lot of special-case
code for constructors and destructors, including
ActOnConstructor/ActOnDeclarator and special lookup rules in
LookupDecl. The result is far more uniform and manageable.

Diagnose the redeclaration of member functions.

Douglas Gregor 91f84216f7 Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).

Douglas Gregor b0846b0f51 Add support for calls to dependent names within templates, e.g.,
template<typename T> void f(T x) {
    g(x); // g is a dependent name, so don't even bother to look it up
    g(); // error: g is not a dependent name
  }

Note that when we see "g(", we build a CXXDependentNameExpr. However,
if none of the call arguments are type-dependent, we will force the
resolution of the name "g" and replace the CXXDependentNameExpr with
its result.

GCC actually produces a nice error message when you make this
mistake, and even offers to compile your code with -fpermissive. I'll
do the former next, but I don't plan to do the latter.

Douglas Gregor 5101c24f60 Representation of template type parameters and non-type template
parameters, with some semantic analysis:
  - Template parameters are introduced into template parameter scope
  - Complain about template parameter shadowing (except in Microsoft mode)

Note that we leak template parameter declarations like crazy, a
problem we'll remedy once we actually create proper declarations for
templates. 

Next up: dependent types and value-dependent/type-dependent
expressions.

Chris Lattner f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Chris Lattner 86d7d91366 Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make it
assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

Chris Lattner bc495d775f move the Diag method for Sema to be inline. This shrinks the release-asserts
clang executable (when built with gcc 4.2 on the mac) from 14519740 to 
14495028 bytes.  This shrinks individual object files as well: SemaChecking
from 23580->22248, SemaDeclObjc from 61368->57376, SemaExpr from 
115628->110516, as well as several others.

Chris Lattner ec7f7732f1 remove the type_info identifier cache. Compared to the cost
of doing the lookup_decl, the hash lookup is cheap.  Also,
typeid doesn't happen enough in real world code to worry about
it.

I'd like to eventually get rid of KnownFunctionIDs from Sema
also, but today is not that day.

Chris Lattner 0e73b2c352 compared to the rest of the code in Sema::GetStdNamespace(),
looking up the "std" identifier is trivial.  Just do it, particularly
since this is only done if the namespace hasn't already been looked up.
