This is far from implementing all the rules given by
http://www.webkit.org/coding/coding-style.html
The important new feature is the support for styles that don't have a
column limit. For such styles, clang-format will (at the moment) simply
respect the input's formatting decisions within statements.

The help text was wrong, and we already provide help text on the
option that actually changes anything, i.e. -fdiagnostics-show-note-include-stack.

function-like macro. Clang will attempt to correct the arguments by detecting
braced initializer lists:
1) If possible, suggest parentheses around arguments
containing braced lists which will give the proper number of arguments.
2) If a braced list is detected at the start of a macro argument, it cannot be
corrected by parentheses. Instead, just point out the location of these
braced lists.

bool, half, pointers and structs / unions containing any
of these are not allowed. Does not yet reject size_t and
related integer types that are also disallowed.

Switch some warnings over to errors which should never have been warnings
in the first place. (Also, a minor fix to the preprocessor rules for
integer literals while I'm here.)

The headers in the compiler's own resource include directory are
system headers, which means we don't stat() them eagerly when loading
a module. Use module.map as a proxy for these headers and the compiler
itself. Fixes <rdar://problem/13856838>.

Summary:
Add support for overloaded matchers.
This composes with other features, like supporting polymorphic matchers.

Based on Peter Collingbourne's destructor patches.
Prior to this change, clang was considering ?1 to be the complete
destructor and the base destructor, which was wrong. This lead to
crashes when clang tried to emit two LLVM functions with the same name.
In this ABI, TUs with non-inline dtors might not emit a complete
destructor. They are emitted as inline thunks in TUs that need them,
and they always delegate to the base dtors of the complete class and its
virtual bases. This change uses the DeferredDecls machinery to emit
complete dtors as needed.
Currently in clang try body destructors can catch exceptions thrown by
virtual base destructors. In the Microsoft C++ ABI, clang may not have
the destructor definition, in which case clang won't wrap the virtual
virtual base destructor calls in a try-catch. Diagnosing this in user
code is TODO.
Finally, for classes that don't use virtual inheritance, MSVC always
calls the base destructor (?1) directly. This is a useful code size
optimization that avoids emitting lots of extra thunks or aliases.
Implementing it also means our existing tests continue to pass, and is
consistent with MSVC's output.
We can do the same for Itanium by tweaking GetAddrOfCXXDestructor, but
it will require further testing.

No functionality change.
In Sema helper functions:
* renamed isTypeName as HasTypenameKeyword
In UsingDecl:
* renamed get/setUsingLocation to get/setUsingLoc
* renamed is/setTypeName as has/setTypename

A constructor for an abstract class does not call constructors for virtual
base classes, so it is not an error if no initializer is present for the
virtual base and the virtual base cannot be default initialized.
Also provide a (disabled by default, for now) warning for the case where a
virtual base class's initializer is ignored in an abstract class's constructor,
and address a defect in DR257 where it was not carried through to C++11's rules
for implicit deletion of special member functions.
Based on a patch by Maurice Bos.

optimize, to follow the permissions granted in N3664. Under those rules, only
calls generated by new-expressions and delete-expressions are permitted to be
optimized, and direct calls to ::operator new and ::operator delete must be
treated as normal calls.
llvm-svn: 186799
The functionality is equivalent to the GCC attribute. Variables of tagged
types will be warned about as unused if they are not used in any way
except for possible (even non-trivial) ctors/dtors called. Useful for tagging
classes like std::string (which is not part of this commit).
llvm-svn: 186765
Diag ID is used throughout clang as a sentinel id meaning "this is an
invalid diagnostic id." Confusingly, Diag ID maps to a valid, usable,
diagnostic id. Instead, start diagnostic ids at ID one.
Incidently, remove an unused element from StaticDiagInfo.
llvm-svn: 186760
This is the same way GenericSelectionExpr works, and it's generally a
more consistent approach.
A large part of this patch is devoted to caching the value of the condition
of a ChooseExpr; it's needed to avoid threading an ASTContext into
IgnoreParens().
Fixes <rdar://problem/14438917>.

This patch essentially removes all the FIXMEs following calls to DeduceTemplateArguments() that want to keep track of deduction failure info.

Summary:
Add printToStream*(llvm::raw_ostream&) methods to Diagnostics, and reimplement everything based on streams instead of concatenating strings.
Also, fix some functions to start with lowercase to match the style guide.

Canonical types are unchanged. The type printer had to be changed to
avoid printing any non-default implicit calling convention as well as
the calling convention attribute.
