pluralizing the message, e.g.,

Douglas Gregor f5b160f89c When computing the canonical profile of a DeclRefExpr or MemberExpr,
don't include the nested-name-specifier or template arguments: they
were only relevant when resolving the declaration. Fixes PR7460.

Douglas Gregor 603d81bf8d When forming a function call or message send expression, be sure to
strip cv-qualifiers from the expression's type when the language calls
for it: in C, that's all the time, while C++ only does it for
non-class types. 

Centralized the computation of the call expression type in
QualType::getCallResultType() and some helper functions in other nodes
(FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant
callers of getResultType() to getCallResultType().

Fixes PR7598 and PR7463, along with a bunch of getResultType() call
sites that weren't stripping references off the result type (nothing
stripped cv-qualifiers properly before this change).

Douglas Gregor dbb2806a7b Do not generate LLVM IR for available_externally function bodies at
-O0, since we won't be using the definitions for anything anyway. For
lib/System/Path.o when built in Debug+Asserts mode, this leads to a 4%
improvement in compile time (and suppresses 440 function bodies).

Chandler Carruth 65a38183f0 Fix another aspect of PR7047, macro expansions. Previously, this was hacked
around by exempting enums from the check, but this doesn't handle a lot of
cases. A better approach is to directly check if the operator comes from
a macro expansion.

I've removed a reference to the rdar that originally led to the enum
suppression when removing it's overly contrived test case. Let me know if that
number or a more reasilistic test case involving enums is still needed.

Chris Lattner 5a503e9f70 we do in fact have to cache the EOF token returned by the preprocessor.
In the case of backtracking, the cached token lexer will be the only 
lexer on the stack, without this the token stack will be empty and EOF
won't be returned.

This fixes PR7072.

Chris Lattner 1390134c18 Fix PR7617 by not entering ParseFunctionDefinition when
a function prototype is followed by a declarator if we
aren't parsing a K&R style identifier list.

Also, avoid skipping randomly after a declaration if a
semicolon is missing.  Before we'd get:

t.c:3:1: error: expected function body after function declarator
void bar();
^

Now we get:

t.c:1:11: error: invalid token after top level declarator
void foo()
          ^
          ;

Chandler Carruth 17773fcd83 Lay the ground work for resoving PR7047. This doesn't actually fix it because
default arguments to template parameters don't have a DeclContext when
instantiated, and so we can't detect that we're in an instantiation context as
opposed to the definition context. However, it fixes the more commonly-occuring
cases in TMP code that use devolve to this type of tautology after
substitution.

Craig Silverstein 4a5d086b50 Fix a crashing but trying to print a TemplateTemplateParmDecl
for code like this:
   template<template<typename T> class U> class V {};

The problem is that the DeclPrinter assumed all TemplateDecls
have a getTemplatedClass(), but template template params don't
(so we got a NULL dereference).  The solution is to detect if
we're a template template param, and construct the template
class name ('class U') specially in this case.
