71ba5f27de ActOnTagDefinitionError is supposed to 'unwind' ActOnTagStartDefinition, not 
ActOnStartCXXMemberDeclaration.  We haven't started the field collector on this
class yet, so don't stop it.  Fixes a crash in the VS buildbot and a memory error
on all the others.

319aa6c4b5 Remove warning about shadowing a built-in; built-ins aren't actually 
considered to be a part of the translation unit unless they're named
in a way that brings them into existence.

802b77601e Introduce a new BufferResult class to act as the return type of 
SourceManager's getBuffer() (and similar) operations. This abstract
can be used to force callers to cope with errors in getBuffer(), such
as missing files and changed files. Fix a bunch of callers to use the
new interface.

Add some very basic checks for file consistency (file size,
modification time) into ContentCache::getBuffer(), although these
checks don't help much until we've updated the main callers (e.g.,
SourceManager::getSpelling()).

ea16606fcd During C++ name lookup, use DeclContext::Equals() rather than 
comparing DeclContext pointers, to avoid having to remember to call
getPrimaryContext() everywhere. This is the last part PR6594.

6623006249 Implement C++ [temp.local]p8, which specifies that a template 
parameter hides a namespace-scope declararion with the same name in an
out-of-line definition of a template. The lookup requires a strange
interleaving of lexical and semantic scopes (go C++), which I have not
yet handled in the typo correction/code completion path.

Fixes PR6594.

3e11ebebc8 Remember declaration scope qualifiers in the AST. Imposes no memory overhead 
on unqualified declarations.

Patch by Enea Zaffanella!  Minimal adjustments:  allocate the ExtInfo nodes
with the ASTContext and delete them during Destroy().  I audited a bunch of
Destroy methods at the same time, to ensure that the correct teardown was
being done.

86838aafee For ivars created using @synthesize, set their DeclContext to be 
the @implementation (instead of the @interface) and actually add
the ivar to the DeclContext (which we weren't doing before).

This allows us to simplify ASTContext::CollectNonClassIvars() by
removing ASTContext::CollectProtocolSynthesizedIvars().  Now all
ivars can be found by either inspecting the ObjCInterfaceDecl and
its companion ObjCImplementationDecl.

58f10c3380 Maintain type source information for functions through template 
instantiation.  Based on a patch by Enea Zaffanella!  I found a way to
reduce some of the redundancy between TreeTransform's "standard"
FunctionProtoType transformation and TemplateInstantiator's override,
and I killed off the old SubstFunctionType by adding type source info
for the last cases where we were creating FunctionDecls without TSI
(at least that get passed through template instantiation).

bbbbe4eaaf Split C++ friend declarations into their own header/implementation file. 
I'm expecting this portion of the AST to grow and change, and I'd like to
be able to do that with minimal recompilation.  If this proves unnecessary
when access control is fully-implemented, I'll fold the classes back into
DeclCXX.h.

e78aac41de Create a new InjectedClassNameType to represent bare-word references to the 
injected class name of a class template or class template partial specialization.
This is a non-canonical type;  the canonical type is still a template 
specialization type.  This becomes the TypeForDecl of the pattern declaration,
which cleans up some amount of code (and complicates some other parts, but
whatever).

Fixes PR6326 and probably a few others, primarily by re-establishing a few
invariants about TypeLoc sizes.
