8f1439bd0c [C++11] Using std::unique_ptr to ensure that Argument objects do not leak (since clang-tblgen isn't long-lived, the old leak is probably acceptable, but it offended my senses nonetheless).

757fcd6d1f [cleanup] Re-sort includes with llvm/utils/sort_includes.py and fix 
a missing include from CLog.h.

CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.

ea6668c4e8 Moving the documentation for the type safety checking attributes into AttrDocs. If a custom heading is provided, do not automatically generate the alternate spelling list. This is necessary because some attributes have distinct semantic spellings and meanings, but use the same semantic attribute internally. Such attributes should have multiple elements in their documentation list, but not show all spellings. At some point, it would be nice to have a way to attach the documentation element to a specific spelling for these cases.

4de1b584cd Refactored the way attribute category headers are handled so that it is possible to use custom categories. This allows for moving the consumable attributes (consumable, callable_when, return_typestate, etc) to be grouped together, with a content heading, like they were in the language extensions documentation. Moved the consumable attribute documentation from the language extensions into the attribute documentation table.

06bd44b3e8 Forcing it to be an error when there is no Documentation list specified for an attribute. This is a bit of a (harmless) hack, but the FIXME explains why and when this hack can be removed. It's a justified hack because this prevents attribute authors from forgetting to add documentation when they add a new attribute.

97dba048a3 Implements a declarative approach to documenting individual attributes in Clang via a Documentation tablegen class. Also updates the internals manual with information about how to use this new, required, documentation feature. 
This patch adds some very, very sparse initial documentation for some attributes. Additional effort from attribute authors is greatly appreciated.

4bb0980d96 MS ABI: Add support for #pragma pointers_to_members 
Introduce a notion of a 'current representation method' for
pointers-to-members.

When starting out, this is set to 'best case' (representation method is
chosen by examining the class, selecting the smallest representation
that would work given the class definition or lack thereof).

This pragma allows the translation unit to dictate exactly what
representation to use, similar to how the inheritance model keywords
operate.

N.B.  PCH support is forthcoming.

35db2b3d4c Consolidating several table-generated files containing parser-related string switches into a single file. This reduces build-related complexity by replacing four separate projects (and table-gen instantiations) with a single one.

c669cc0d77 Add a new attribute meta-spelling called "GCC" -- it widens into being a GNU spelling, and a CXX11 spelling with the namespace "gnu". It also sets a bit on the spelling certifying that it is known to GCC. From this, we can warn about the extension appropriately. As a consequence, the FunctionDefinition functionality is completely removed. 
Replacing the functionality from r199676, which didn't solve the problem as elegantly.

81cb8cbfa6 Adds a getSemanticSpelling function to semantic attribute subclasses which have a meaningful semantic spelling. Adds a sibling function to parsed attribtues (via AttributeList) for getting the semantic spelling, if one were to exist. This can be used for cleaner code that deals directly with the semantic spellings (such as the MSInheritance attribute).

bc909618f2 If an attribute has a semantically meaningful spelling (such as ArgumentWithTypeTagAttr or MSInheritanceAttr), display the spelling used for the attribute as part of the AST dump. This should ease debugging the AST for these attributes. Attributes without semantically meaningful spelling variations are not affected.

9a99e0da5a Remove some hard-coded specialness for thread-safety attributes from the parser, and made it more declarative. If an attribute is allowed to appear on a function definition when late parsed, it can now use the FunctionDefinition attribute subject. It's treated as a FunctionDecl for most purposes, except it also gets exposed on the AttributeList so that it can be used while parsing.

12b9f6535b Factored some function-like type reasoning out of SemaDeclAttr and onto Decl itself. This allows for more declarative subjects in attribute tablegen where the attribute appertains to something function-like, but not strictly a FunctionDecl.

36a5350e51 Distinguish between attributes explicitly written at the request of the user, and attributes implicitly generated to assist in bookkeeping by the compiler. This is done so by table generating a CreateImplicit method for each attribute. 
Additionally, remove the optional nature of the spelling list index when creating attributes. This is supported by table generating a Spelling enumeration when the spellings for an attribute are distinct enough to warrant it.

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).

ab7691c4ce Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out.

5553d0d4ca Sort all the #include lines with LLVM's utils/sort_includes.py which

3e424b5070 Teach the diagnostics engine about the Attr type to make reporting on semantic attributes easier (and not require hard-coded strings). This requires a getSpelling() function on the Attr class, which is table-driven. Updates a handful of cases where a hard-coded string was being used to test the functionality out. Updating associated test cases for the improved quoting.
