3256d04d22 Refactor ActOnDeclarationNameExpr into a "parsing action" part and a
"semantic analysis" part. Use the "semantic analysis" part when
performing template instantiation on a DeclRefExpr, rather than an ad
hoc list of rules to construct DeclRefExprs from the instantiation.

A test case for this change will come in with a large commit, which
illustrates what I was actually trying to work on.

cfbfe78e9e De-ASTContext-ify DeclContext.
Remove ASTContext parameter from DeclContext's methods. This change cascaded down to other Decl's methods and changes to call sites started "escalating".
Timings using pre-tokenized "cocoa.h" showed only a ~1% increase in time run between and after this commit.

b4b64ca752 Remove the ASTContext parameter from the attribute-related methods of Decl.
The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.

This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

4adbc6d947 Implicit instantiation for function template specializations.
For a FunctionDecl that has been instantiated due to template argument
deduction, we now store the primary template from which it was
instantiated and the deduced template arguments. From this
information, we can instantiate the body of the function template.

ad3f2fcf43 Improved semantic analysis and AST respresentation for function
templates.

For example, this now type-checks (but does not instantiate the body
of deref<int>):

  template<typename T> T& deref(T* t) { return *t; }

  void test(int *ip) {
    int &ir = deref(ip);
  }

Specific changes/additions:
  * Template argument deduction from a call to a function template.
  * Instantiation of a function template specializations (just the
  declarations) from the template arguments deduced from a call.
  * FunctionTemplateDecls are stored directly in declaration contexts
  and found via name lookup (all forms), rather than finding the
  FunctionDecl and then realizing it is a template. This is
  responsible for most of the churn, since some of the core
  declaration matching and lookup code assumes that all functions are
  FunctionDecls.

0b6a6242ed Rework the way we track which declarations are "used" during
compilation, and (hopefully) introduce RAII objects for changing the
"potentially evaluated" state at all of the necessary places within
Sema and Parser. Other changes:

  - Set the unevaluated/potentially-evaluated context appropriately
    during template instantiation.
  - We now recognize three different states while parsing or
    instantiating expressions: unevaluated, potentially evaluated, and
    potentially potentially evaluated (for C++'s typeid).
  - When we're in a potentially potentially-evaluated context, queue
    up MarkDeclarationReferenced calls in a stack. For C++ typeid
    expressions that are potentially evaluated, we will play back
    these MarkDeclarationReferenced calls when we exit the
    corresponding potentially potentially-evaluated context.
  - Non-type template arguments are now parsed as constant
    expressions, so they are not potentially-evaluated.

c9c02ed8f4 Keep track of when declarations are "used" according to C and
C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

fb4330f255 First step toward fixing <rdar://problem/6613046> refactor clang objc type representation.
Add a type (ObjCObjectPointerType) and remove a type (ObjCQualifiedIdType).

This large/tedious patch is just a first step. Next step is to remove ObjCQualifiedInterfaceType. After that, I will remove the magic TypedefType for 'id' (installed by Sema). This work will enable various simplifications throughout clang (when dealing with ObjC types). 

No functionality change.

9e81b02ec5 Don't allow defining a block with a non-prototype type. Remove a
hack which introduces some strange inconsistencies in compatibility 
for block pointers.

Note that unlike an earlier revision proposed on cfe-commits, this patch 
still allows declaring block pointers without a prototype.

fcbf7d2baf PR4287: allow a variadic prototype to make a subsequent K&R style
definition variadic.  I'm not completely sure it's legal, but the 
standard can be interpreted as making it legal, and gcc seems to think 
it's legal, so I didn't add an extension warning.

a8db954f24 Representation of and template instantiation for member
expressions. This change introduces another AST node,
CXXUnresolvedMemberExpr, that captures member references (x->m, x.m)
when the base of the expression (the "x") is type-dependent, and we
therefore cannot resolve the member reference yet.

Note that our parsing of member references for C++ is still quite
poor, e.g., we don't handle x->Base::m or x->operator int.
