Updated the thread safety attribute definitions to have subjects defined. These are based off what SemaDeclAttr.cpp is checking for in terms of diagnostic reporting. No functional change intended.

There is no such thing as __declspec(ms_struct), this is a GNU attribute. Switched the attribute to have the proper spelling, gave it a subject, updated the warning to be more accurate, and updated the test case as appropriate.

[-cxx-abi microsoft] Emit linkonce_odr definitions for declarations of static data members with inline initializers (PR17689)

This makes Clang emit a linkonce_odr definition for 'val' in the code below,
to be compatible with MSVC-compiled code:

  struct Foo {
    static const int val = 1;
  };

clang-format: Improve formatting of ObjC method expressions.

In particular, make breaking after a parameter's ":" more of a last
resort choice as it significantly affects the readability gained by
aligning the parameters.

Before (in Chromium style - which doesn't allow bin-packing):
  {
    popup_window_.reset([[RenderWidgetPopupWindow alloc]
        initWithContentRect:
            NSMakeRect(
                origin_global.x, origin_global.y, pos.width(), pos.height())

                    backing:NSBackingStoreBuffered
                      defer:NO]);
  }

Provide better diagnostic wording for initializers on static
data member definitions when the variable has an initializer
in its declaration.

For the following code:

  struct S {
    static const int x = 42;
  };
  const int S::x = 42;

This patch changes the diagnostic from:

  a.cc:4:14: error: redefinition of 'x'
  const int S::x = 42;
               ^
  a.cc:2:20: note: previous definition is here
    static const int x = 42;
                     ^
to:

  a.cc:4:18: error: static data member 'x' already has an initializer
  const int S::x = 42;
                   ^
  a.cc:2:24: note: previous initialization is here
    static const int x = 42;
                         ^

Add new attribute 'objc_suppress_protocol' to suppress protocol conformance for a class.

The idea is to allow a class to stipulate that its methods (and those
of its parents) cannot be used for protocol conformance in a subclass.
A subclass is then explicitly required to re-implement those methods
of they are present in the class marked with this attribute.

Currently the attribute can only be applied to an @interface, and
not a category or class extension.  This is by design.  Unlike
protocol conformance, where a category can add explicit conformance
of a protocol to class, this anti-conformance really needs to be
observed uniformly by all clients of the class.  That's because
the absence of the attribute implies more permissive checking of
protocol conformance.

This unfortunately required changing method lookup in ObjCInterfaceDecl
to take an optional protocol parameter.  This should not slow down
method lookup in most cases, and is just used for protocol conformance.

Revert "Add new attribute 'objc_suppress_protocol' to suppress protocol conformance for a class."

After implementing this patch, a few concerns about the language
feature itself emerged in my head that I had previously not considered.
I want to resolve those design concerns first before having
a half-designed language feature in the tree.

ARM: define & use __ARM_NEON on ARM32 (as per ACLE)

There seem to be quite a few references to the old macro __ARM_NEON__ on the
internet, so I don't think it's a good idea to remove it entirely (at least
yet), but the canonical name does not have the trailing underscores so we
should use that ourselves.

Better implementation of JavaScript === and !== operators.

Now based on token merging. Now they are not only prevented from being
