Hack: Add 'PathDiagnostic::flattenLocations()'. Because PlistDiagnosticClient
can use a PathLocation after any reference Stmts are reclaimed,
flattenLocation() converts those references to statements to source ranges.

fix a FIXME, providing accurate source range info for DeclStmt's.  The end
of the range is now the ';' location.  For something like this:

$ cat t2.c

#define bool int
void f(int x, int y) {
bool b = !x && y;
}

We used to produce:
$ clang-cc t2.c -ast-dump
typedef char *__builtin_va_list;

void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
  (DeclStmt 0x2201ef0 <line:2:14>                   <----
    0x2201a20 "int b =
      (BinaryOperator 0x2201ed0 <line:4:10, col:16> 'int' '&&'
        (UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'
          (DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
        (DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")

Now we produce:

$ clang-cc t2.c -ast-dump
typedef char *__builtin_va_list;

void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
  (DeclStmt 0x2201ef0 <line:2:14, line:4:17>         <------
    0x2201a20 "int b =

        (UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'
          (DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
        (DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")

Plus, reword a extension warnings to avoid talking about "ISO C" when
the extension might also be available in C++ or C++0x.

Make parsing a semantic analysis a little more robust following Sema
failures that involve malformed types, e.g., "typename X::foo" where
"foo" isn't a type, or "std::vector<void>" that doens't instantiate
properly.

Similarly, be a bit smarter in our handling of ambiguities that occur
in Sema::getTypeName, to eliminate duplicate error messages about
ambiguous name lookup.

This eliminates two XFAILs in test/SemaCXX, one of which was crying
out to us, trying to tell us that we were producing repeated error
messages.

CodeGenModule::GetAddrOfConstantCFString():

Remove warning from CheckObjCString.

As the FIXME in the test case indicates, I still have a bug to work out (apparently with \u handling).
