The later assumption is patently false, but this was already broken -- this situation is conceptually impossible, my feeling is we should fix SourceManager and friends to make it impossible in practice as well. However, we need to fix PR5662 and perhaps some other things involving memory buffers first. In the short term I'm pretty sure this is reliable.
Chris, Argiris, is this going to break anything that wasn't already broken?

in diagnostics when we fail to open a file. This allows us to
report things like:
$ clang test.c -I.
test.c:2:10: fatal error: error opening file './foo.h': Permission denied
#include "foo.h"

implicit member access to a specific declaration, go ahead and create
it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as
appropriate. Otherwise, create an UnresolvedMemberExpr or
DependentScopeMemberExpr with a null base expression.
By representing implicit accesses directly in the AST, we get the ability
to correctly delay the decision about whether it's actually an instance
member access or not until resolution is complete. This permits us
to correctly avoid diagnosing the 'problem' of 'MyType::foo()'
where the relationship to the type isn't really known until instantiation.

common to both parsing and template instantiation, so that we'll find
overridden virtuals for member functions of class templates when they
are instantiated.
Additionally, factor out the checking for pure virtual functions, so
that it will be executed both at parsing time and at template
instantiation time.
These changes fix PR5656 (for real), although one more tweak
w.r.t. member function templates will be coming along shortly.

ValueDecl, because that isn't always the case in ill-formed
code. Diagnose a common mistake (forgetting to provide a template
argument list for a class template, PR5655) and dyn_cast so that we
handle the general problem of referring to a non-value declaration
gracefully.

Also, add an -ast-from-source option to index-test which allows index-test to
run on source files directly.

Highlights include:
Fix __cxa_begin_catch so it now returns a value.
Added getUnwindResumeOrRethrowFn helper to build up calls to
_Unwind_Resume_or_Rethrow.
Broke out object copying code into CopyObject from EmitCXXThrowExpr.
Built up another version of CopyObject that can copy from memory for
use in the catch parameter code.
RTTI generation for type matching for catch.
Code to check for the type match for catch.
Code to generate the catch parameter, WIP, need make sure references
and pointers and copy ctors work.

- I'm not even sure if this mode is still useful given the other scanning mode;

ASTContext instead of malloc. Besides reducing malloc traffic, this
also removes a source of memory leaks when using a BumpPtrAllocator
for the allocator of ASTContext. There are still leaks when using
MallocAllocator because Decl::Destroy() isn't fully finished.

Create a new UnresolvedMemberExpr for these lookups. Assorted hackery
around qualified member expressions; this will all go away when we
implement the correct (i.e. extremely delayed) implicit-member semantics.
