In line with SemaOpenMP.cpp, etc. CUDA-specific semantic analysis code goes into
a separate file. This is in anticipation of adding extra functionality here in
the near future.
No change in functionality.

This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

correctly aligned. Not performing such computations led to misaligned loads,
which crash on some platforms and are generally bad on other platforms.
The implementation of TypeLocBuilder::pushImpl is rather messy; code using
TypeLocBuilder accidentally assumes that partial TypeLocs are
laid out like a complete TypeLoc. As a followup, I intend to work on
fixing the TypeLocBuilder API to avoid exposing partial TypeLocs; this should
substantially simplify the implemementation.
Fixes PR16144.

Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td.
This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute.
When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and
name, then passed to Attr that will use the index to print itself.
Thanks to Richard Smith for the idea and review.

diagnostics implemented -- see testcases.
I created a new TableGen file for comment diagnostics,
DiagnosticCommentKinds.td, because comment diagnostics don't logically
fit into AST diagnostics file. But I don't feel strongly about it.
This also implements support for self-closing HTML tags in comment
lexer and parser (for example, <br />).
In order to issue precise diagnostics CommentSema needs to know the
declaration the comment is attached to. There is no easy way to find a decl by
comment, so we match comments and decls in lockstep: after parsing one
declgroup we check if we have any new, not yet attached comments. If we do --
then we do the usual comment-finding process.
It is interesting that this automatically handles trailing comments.
We pick up not only comments that precede the declaration, but also
comments that *follow* the declaration -- thanks to the lookahead in
the lexer: after parsing the declgroup we've consumed the semicolon
and looked ahead through comments.
Added -Wdocumentation-html flag for semantic HTML errors to allow the user to
disable only HTML warnings (but not HTML parse errors, which we emit as
warnings in -Wdocumentation).

very simple semantic analysis that just builds the AST; minor changes for lexer
to pick up source locations I didn't think about before.
Comments AST is modelled along the ideas of HTML AST: block and inline content.
* Block content is a paragraph or a command that has a paragraph as an argument
or verbatim command.
* Inline content is placed within some block. Inline content includes plain
text, inline commands and HTML as tag soup.

express library-level dependencies within Clang.
This is no more verbose really, and plays nicer with the rest of the
CMake facilities. It should also have no change in functionality.

That commit added a new library just to hold the RawCommentList. I've
started a discussion on the commit thread about whether that is really
meritted -- it certainly doesn't seem necessary at this stage.
However, the immediate problem is that the AST library has a hard
dependency on the Comment library, but the dependencies were set up
completely backward. In addition to the layering violation, this had an
unfortunate effect if scattering the Comments library dependency
throughout the build system, but inconsistently so -- several parts of
the CMake dependencies were missing and only showed up due to transitive
deps or the fact that the target wasn't being built by tho bots.
It turns out that the Comments library can't (currently) be a well
formed layer *below* the AST library either, as it has an API that
accepts an ASTContext. That parameter is currently unused, so maybe that
was a mistake?
Anyways, it really seems like this is logically part of the AST --
that's the whole point of the ASTContext providing access to it as far
as I can tell -- so I've merged it into the AST library to solve the
immediate layering violation problems and remove some of the churn from
our library dependencies.

(yet), testing of this is necessarily quite minimal.

This submission improves Clang sema handling by using Clang tablegen
to generate common boilerplate code. As a start, it implements AttributeList
enumerator generation and case statements for AttributeList::getKind.
A new field "SemaHandler" is introduced in Attr.td and by default set to 1
as most of attributes in Attr.td have semantic checking in Sema. For a small
number of attributes that don't appear in Sema, the value is set to 0.
Also there are a small number of attributes that only appear in Sema but not
in Attr.td. Currently these attributes are still hardcoded in Sema AttributeList.

instead of having a special-purpose function.
- ActOnCXXDirectInitializer, which was mostly duplication of
AddInitializerToDecl (leading e.g. to PR10620, which Eli fixed a few days
ago), is dropped completely.
- MultiInitializer, which was an ugly hack I added, is dropped again.
- We now have the infrastructure in place to distinguish between
int x = {1};
int x({1});
int x{1};
-- VarDecl now has getInitStyle(), which indicates which of the above was used.
-- CXXConstructExpr now has a flag to indicate that it represents list-
initialization, although this is not yet used.
- InstantiateInitializer was renamed to SubstInitializer and simplified.
- ActOnParenOrParenListExpr has been replaced by ActOnParenListExpr, which
always produces a ParenListExpr. Placed that so far failed to convert that
back to a ParenExpr containing comma operators have been fixed. I'm pretty
sure I could have made a crashing test case before this.
The end result is a (I hope) considerably cleaner design of initializers.
More importantly, the fact that I can now distinguish between the various
initialization kinds means that I can get the tricky generalized initializer
test cases Johannes Schaub supplied to work. (This is not yet done.)
This commit passed self-host, with the resulting compiler passing the tests. I
hope it doesn't break more complicated code. It's a pretty big change, but one
that I feel is necessary.

This object controls when the warnings are executed, allowing the client code
in Sema to selectively disable warnings as needed.
Centralizing the logic for analysis-based warnings allows us to optimize
when and how they are run.
Along the way, remove the redundant logic for the 'check fall-through' warning
for blocks; now the same logic is used for both blocks and functions.
