Driver: Handle properly calling dsymutil when source input is
preceeded by a linker input flag.
 - <rdar://problem/6757236> clang should make a dSYM when going
   straight from source to binary

 - This still matches gcc, but the right way to solve this would be to
   detect the situation we care about (we are compiling from source
   and linking in one step), instead of looking at the suffix of the
   input file. The Tool doesn't quite have enough information to do
   this yet, however.

 - Also, find the suffix correctly.

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>         <------

          (DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
        (DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")

Fix a bug in declaration of property in continuation
class which was exposed by implementation of
objc2's nonfragile abi code gen.

Add code modification hints to various parsing-related diagnostics.

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():
- Finish up support for converting UTF8->UTF16 to support ObjC @"string" constants.

Remove warning from CheckObjCString.

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