Richard Smith 87f5dc53b2 Add diagnostics for comma at end of enum and for extra semicolon at namespace
scope to -Wc++11-extensions. Move extra semicolon after member function
definition diagnostic out of -pedantic, since C++ allows a single semicolon
there. Keep it in -Wextra-semi, though, since it's still questionable.

Richard Smith 09f76ee63c Improve the diagnostic when a comma ends up at the end of a declarator group
instead of a semicolon (as sometimes happens during refactorings). When such a
comma is seen at the end of a line, and is followed by something which can't
possibly be a declarator (or even something which might be a plausible typo for
a declarator), suggest that a semicolon was intended.

Chris Lattner 005fc1bbcf fix PR6782, an accept invalid. We weren't emitting the diagnostic
returned by SetTypeSpecType.

John McCall 8bc2a70dfe Don't infinite-loop if TryAnnotateCXXScopeToken fails to annotate but doesn't
signal an error.  This can happen even when the current token is '::' if
this is a ::new or ::delete expression.

This was an oversight in my recent parser refactor;  fixes PR 5825.

Chris Lattner 916dbf114a improve diagnostics for C++ struct ; issues. Before:
t.cc:4:3: error: expected ';' at end of declaration list
  int y;
  ^
t.cc:6:1: error: expected ';' at end of declaration list
};
^

After:

t.cc:3:8: error: expected ';' at end of declaration list
  int x
       ^
       ;
t.cc:5:8: error: expected ';' at end of declaration list
  int z
       ^

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Chris Lattner 3c674cf804 If we enter parens, colons can become un-sacred, allowing us to emit
a better diagnostic in the second example.

Chris Lattner 17c3b1f278 fix incorrect parsing of bitfields pointed out by Doug. I chose
to use ColonProtectionRAIIObject in the C codepath even though it
won't matter for consistency.

Chris Lattner 1c4280328d reapply my patch for PR4451, which improves diagnostics for :: vs : confusion.
This time with a fix to bail out when in a dependent context.

Chris Lattner 71d5bf1c5d implement PR4451, improving error recovery for a mistaken : where a :: was
intended.  On the first testcase in the bug, we now produce:

cxx-decl.cpp:12:2: error: unexpected ':' in nested name specifier
y:a a2;
 ^
 ::

instead of:

t.cc:8:1: error: C++ requires a type specifier for all declarations
x:a a2;
^
t.cc:8:2: error: invalid token after top level declarator
x:a a2;
 ^
 ;
t.cc:9:11: error: use of undeclared identifier 'a2'
x::a a3 = a2;
          ^

Chris Lattner 869c6610c7 Fix some C++ error recovery problems in init declarator parsing
that I noticed working on other things.

Instead of emitting:

t2.cc:1:8: error: use of undeclared identifier 'g'
int x(*g);
       ^
t2.cc:1:10: error: expected ')'
int x(*g);
         ^
t2.cc:1:6: note: to match this '('
int x(*g);
     ^

We now only emit:

t2.cc:1:7: warning: type specifier missing, defaults to 'int'
int x(*g);
      ^


Note that the example in SemaCXX/nested-name-spec.cpp:f4 is still
not great, we now produce both of:

void f4(undef::C); // expected-error {{use of undeclared identifier 'undef'}} \
                      expected-error {{variable has incomplete type 'void'}}

The second diagnostic should be silenced by something getting marked invalid.
I don't plan to fix this though.
