Richard Smith 8e1ac33ec7 Support C11 _Atomic type qualifier. This is more-or-less just syntactic sugar for the _Atomic type specifier.

Argyrios Kyrtzidis c36633c47a [Parser] Don't code-complete twice.
When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.

Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.

Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

Richard Smith 2386c8b221 Per the grammar in [dcl.dcl]p1, a simple-declaration can only have attributes
if it has declarators. We were missing the check for this in a couple of places.

are placed after the access-specifier or 'virtual' in a base specifier.

Dmitri Gribenko d1c91f1763 Accept over-qualified constructor in MSVC emulation mode
MSVC accepts this:

class A {
  A::A();
};

Clang accepts regular member functions with extra qualification as an MS
extension, but not constructors.  This changes the parser to defer rejecting
qualified constructors so that the same Sema logic can apply to constructors as
regular member functions.  This also improves the error message when MS
extensions are disabled (in my opinion). Before it was:

/Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers
  A::A();
  ~~~~ ^
1 error generated.

After:

/Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A'
  A::A();
  ~~~^
1 error generated.

Richard Smith 810ad3eb44 Downgrade 'attribute ignored when parsing type' from error to warning, to match
the diagnostic's warn_ name. Switch some places (notably C++11 attributes)
which really wanted an error over to a different diagnostic. Finally, suppress
the diagnostic entirely for __ptr32, __ptr64 and __w64, to avoid producing
diagnostics in important system headers.

Richard Smith 0cdcc98200 Replace AS_MSTypespec with AS_Keyword, for representing any attribute spelled
as a keyword. Rationalize existing attributes to use it as appropriate, and to
not lie about some __declspec attributes being GNU attributes. In passing,
remove a gross hack which was discarding attributes which we could handle. This
results in us actually respecting the __pascal keyword again.

Richard Smith e233fbfc16 Finish semantic analysis for [[carries_dependency]] attribute.
This required plumbing through a new flag to determine whether a ParmVarDecl is
actually a parameter of a function declaration (as opposed to a function
typedef etc, where the attribute is prohibited). Weirdly, this attribute (just
like [[noreturn]]) cannot be applied to a function type, just to a function
declaration (and its parameters).

Richard Smith 10876ef571 Implement C++11 semantics for [[noreturn]] attribute. This required splitting
it apart from [[gnu::noreturn]] / __attribute__((noreturn)), since their

affecting the function type, whereas [[noreturn]] does not).

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Michael Han 9407e50b04 Improve diagnostic on C++11 attribute specifiers that appear at wrong syntactic locations around class specifiers.
This change list implemented logic that explicitly detects several combinations of locations where C++11 attribute
specifiers might be incorrectly placed within a class specifier. Previously we emit generic diagnostics like 
"expected identifier" for such cases; now we emit specific diagnostic against the misplaced attributes, this also 
fixed a bug in old code where attributes appear at legitimate locations were incorrectly rejected.

Thanks to Richard Smith for reviewing!

John McCall ea0a39e7ad Accept and pass arguments to __unknown_anytype in argument
positions of Objective-C methods.

It is possible to recover a lot of type information about
Objective-C methods from the reflective metadata for their
implementations.  This information is not rich when it
comes to struct types, however, and it is not possible to
produce a type in the debugger's round-tripped AST which
will really do anything useful during type-checking.
Therefore we allow __unknown_anytype in these positions,
which essentially disables type-checking for that argument.
We infer the parameter type to be the unqualified type of
the argument expression unless that expression is an
explicit cast, in which case it becomes the type-as-written
of that cast.
