Aaron Ballman 05d76eaa21 Removing some attribute magic related to the OpenCL keyword attributes. Instead of mapping them to their semantics as a custom part of the parser, they instead map declaratively through the rest of the attribute system.

Warren Hunt 26b944274e [ms-abi] Small Change to pack+alignment interaction.
This patch makes a small behavioral change to the interaction between 
pack and alignment.  Specifically it makes __declspec(align()) on a 
field change that field's alignment without respect to pack but the 
alignment change to the record alignment as a whole still obeys pack.

Aaron Ballman 09e98ffa5b When determining the attribute's parsed kind, pay attention to the syntax used. This fixes bugs where an attribute has differing GNU and Declspec spellings, but they are treated as the same. Eg) __declspec(aligned) when it should be __attribute__((aligned)), and __attribute__((align)) when it should be __declspec(align).

Warren Hunt badf9e0f84 [ms-abi] Leading VFPtrs don't suppress the leading zero sized flag
The MS-ABI tracks a bit that asserts that the first sub-object is zero 
sized.  This bit is used to add padding between objects if there's the 
potential for zero sized objects to alias.  The bit is still true even 
if the zero sized base is lead by a VFPtr.  This patch makes clang mimic 
that behavior.

Jordan Rose c9176072e6 [analyzer] Add a CFG node for the allocator call in a C++ 'new' expression.
In an expression like "new (a, b) Foo(x, y)", two things happen:
- Memory is allocated by calling a function named 'operator new'.
- The memory is initialized using the constructor for 'Foo'.

Currently the analyzer only models the second event, though it has special
cases for both the default and placement forms of operator new. This patch
is the first step towards properly modeling both events: it changes the CFG
so that the above expression now generates the following elements.

1. a
2. b
3. (CFGNewAllocator)
4. x
5. y
6. Foo::Foo

The analyzer currently ignores the CFGNewAllocator element, but the next
step is to treat that as a call like any other.

The CFGNewAllocator element is not added to the CFG for analysis-based
warnings, since none of them take advantage of it yet.

Hans Wennborg 0f3c10cb8a [ms-cxxabi] Elide dtor access checks for pass-by-val objects in callees
The ABI requires the destructor to be invoked in the callee, but the
standard does not require access checks here so we avoid doing direct
access checks on the destructor.

If we end up needing to define an implicit destructor, we don't skip
access checks for the base class, etc. Those checks are effectively part
of generating the destructor definition, and aren't affected by which TU
the check is performed in.

This patch more cleanly seperates the concepts of Preferred Alignment 
and Required Alignment.  Most notable that changes to Required Alignment

is observable when using pragma pack and non-virtual bases and the use 
of tail padding when laying them out.

Jordan Rose 1a866cd54b [analyzer] Model getters of known-@synthesized Objective-C properties.
...by synthesizing their body to be "return self->_prop;", with an extra
nudge to RetainCountChecker to still treat the value as +0 if we have no
other information.

This doesn't handle weak properties, but that's mostly correct anyway,
since they can go to nil at any time. This also doesn't apply to properties
whose implementations we can't see, since they may not be backed by an
ivar at all. And finally, this doesn't handle properties of C++ class type,
because we can't invoke the copy constructor. (Sema has actually done this
work already, but the AST it synthesizes is one the analyzer doesn't quite
handle -- it has an rvalue DeclRefExpr.)

Modeling setters is likely to be more difficult (since it requires
handling strong/copy), but not impossible.

Warren Hunt d640d7d96e [ms-abi] Refactor Microsoft Record Layout
This patch refactors microsoft record layout to be more "natural".  The 
most dominant change is that vbptrs and vfptrs are injected after the 
fact.  This simplifies the implementation and the math for the offest 
for the first base/field after the vbptr.

Alp Toker bb4b86af83 Implement isCXX11FinalKeyword() in terms of isCXX11VirtSpecifier()
It's not worth keeping two copies of the identifier init and comparison code
just to save a pointer coparison.

This should reduce further once we get proper contextual keywords in the token
stream, so having the identifier checks in one place is a step towards that.

Cleanup only.

Jordan Rose 656fdd55dd [analyzer] Warn about double-delete in C++ at the second delete...
...rather somewhere in the destructor when we try to access something and
realize the object has already been deleted. This is necessary because
the destructor is processed before the 'delete' itself.

Jordan Rose 6ad4cb4eca [analyzer] Remove unused ARCNotOwnedSymbol retain count return effect.
RetainCountChecker has to track returned object values to know if they are
retained or not. Under ARC, even methods that return +1 are tracked by the
system and should be treated as +0. However, this effect behaves exactly
like NotOwned(ObjC), i.e. a generic Objective-C method that actually returns
+0, so we don't need a special case for it.

No functionality change.

Nico Weber 7c81c4a354 [cmake] Write Version.inc at cmake time, not at build time.
In SVN checkouts, clang_revision_tag is rerun on every build, even if nothing
else is dirty.  After this change, Version.inc is only written at cmake time,
so that empty builds run 0 build steps (like r191784 apparently did for git).
