Add a pretty horrible hack to prevent clang from crashing with inconsistent PCH
files.
 - The issue is that PCH uses a stat cache, which may reference files which have
   been deleted or moved. In such cases ContentCache::getBuffer was returning 0
   but most clients are incapable of dealing with this (i.e., they don't).

   For the time being, resolve this issue by just making up some invalid file
   contents and. Eventually we should detect that we are in an inconsistent
   situation and error out with a nice message that the PCH is out of date.

PR5684: Fix refacto, the backend consumer was copying the Diagnostic object,
which meant that hasErrorOccurred() checks to prevent codegen-on-invalid weren't
working.

ASTUnit/CIndex: Explicitly track the top-level decls when using an ASTUnit made
from a source file.
 - This allows CIndex to avoid iterating over all the top-level decls when using
   a PCH, which means we deserialize far fewer decls.

Use PresumedLoc when emitting the 'included from' diagnostics.  For a malformed
test like this:

#line 4 "foo"

#define XX ?

#if XX
#endif

We now emit:

In file included from t.c:7:
foo:7:5: error: invalid token at start of a preprocessor expression
#if XX
    ^
foo:5:12: note: instantiated from:
#define XX ?
           ^

instead of:

In file included from t.c:7:
foo:7:5: error: invalid token at start of a preprocessor expression
#if XX
    ^
./t.h:6:12: note: instantiated from:
#define XX ?
           ^

(where the note doesn't obey #line or print the include stack when needed).

This fixes PR5617
