load in the IndirectField declarations as well.
Field designators in initializer lists depend on traversing the fields
decl chain to find the indirect fields.

Now we have a list of all commands. This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.
With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed). Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands. Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID. Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.
This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state. But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.
Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object. This breaks binary compatibility of CXComment APIs.
Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed. This is a source-incompatible
change for this C API.

unexpanded parameter pack is a pack expansion. Thus, as with a non-type template
parameter which is a pack expansion, it needs to be expanded early into a fixed
list of template parameters.
Since the expanded list of template parameters is not itself a parameter pack,
it is permitted to appear before the end of the template parameter list, so also
remove that restriction (for both template template parameter pack expansions and
non-type template parameter pack expansions).

type is an unqualified objc pointer in arc. Treat it just
as being treated in c++98. This fixes a bogus vararg warning
with -std=c++11. //rdar://12229679

(__builtin_* etc.) so that it isn't possible to take their address.
Specifically, introduce a new type to represent a reference to a builtin
function, and a new cast kind to convert it to a function pointer in the
operand of a call. Fixes PR13195.

__objc_yes/__objc_no to (BOOL)1/(BOOL)0 when
BOOL is declared; otherwise it resorts to
default of 'signed char'. This is important to
selecting the correct Numeric API numberWithBool:
Can't have a clang test for this. Will checkin and
executable llvm test. // rdar://12156616

CheckLValueConstantExpression.
Richard pointed out that using the address of a TLS variable is ok in a
core C++11 constant expression, as long as it isn't part of the eventual
result of constant expression evaluation. Having the check in
CheckLValueConstantExpression accomplishes this.

This makes Clang produce an error for code such as:
__thread int x;
int *p = &x;
The lvalue of a thread-local variable cannot be evaluated at compile
time.

We still need to translate the string, but this at least gets us one step
closer to using the more general EmitAsmStmt() codegen function. No functional
change intended.

not be set for implicit instantiations, remove the FIXME. This should be the
last bit for PR13634. The actual fix happened in r162238.
Motivation: it might be misleading to mark implicit instantiations as
Decl::isImplicit = true. Because then, in order to be consistent, we should
mark all instantiated members as implicit. But the user did actually type the
declaration for the member, but the compiler played with it a little bit.
