Eli Friedman b826a00857 Fix the AST representation for non-type template arguments to encode
enough information so we can mangle them correctly in cases involving
dependent parameter types. (This specifically impacts cases involving
null pointers and cases involving parameters of reference type.)
Fix the mangler to use this information instead of trying to scavenge
it out of the parameter declaration.

Dmitri Gribenko 1da8886915 Comment sema: warn when comment has \deprecated but declaration does not have a
deprecation attribute ('deprecated', 'availability' or 'unavailable').

This warning is under a separate flag, -Wdocumentation-deprecated-sync, so it
can be turned off easily while leaving other -Wdocumentation warnings on.

Argyrios Kyrtzidis b41791d848 When importing a FunctionProtoType::ExtProtoInfo, its ExceptionSpecDecl can point to the
FunctionDecl that we are importing the FunctionProtoType for, in which case we'll have
infinite recursion when importing.

Initially create a FunctionProtoType with null ExceptionSpecDecl/ExceptionSpecTemplate and
update the type in ASTNodeImporter::VisitFunctionDecl after the FunctionDecl has been created.

Argyrios Kyrtzidis 617108990d In StringLiteral::setString make sure that we copy the number of
bytes of the buffer and not the size of the string, otherwise we
may overwrite the buffer if there is a mismatch between the size
of the string and the CharByteWidth, and assertions are disabled.

The bug where this could occur was fixed in r163931.

Dmitri Gribenko 9304d86329 Comment parsing: handle non-builtin commands correctly. After semantic
analysis registers a command, it becomes a "known" command for the lexer, since
it has an ID.  Having this freedom of choice to register a command is a good
thing since BriefParser does not need this.

But the parser should still invoke the correct semantic analysis method
(actOnUnknownCommand) in this case.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
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.

Richard Smith 1fde8ece37 PR9023: A template template parameter whose template parameter list contains an
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).

Hans Wennborg cb9ad9908b Move TLS check from LValueExprEvaluator::VisitVarDecl to

Richard pointed out that using the address of a TLS variable is ok in a

result of constant expression evaluation. Having the check in
CheckLValueConstantExpression accomplishes this.
