This lets us pass functors (and lambdas) without void * tricks. On the

MSVC 2013 ships, as part of its STL implementation, a class named
'_Atomic'. This is unfortunate because this keyword is in conflict with
the C11 keyword with the same name. Our solution was to disable this
keyword when targeting MSVC 2013 and reenable it for 2015.
However, this makes it impossible for clang's headers to make use of
_Atomic. This is problematic in the case of libc++ as it makes heavy
use of this keyword.
Let the keywordness of _Atomic float under certain circumstances:
the body of a class named _Atomic, or a class with a base specifier
named _Atomic, will not have the keyword variant of _Atomic for the
duration of the class body. This is sufficient to allow us to correctly
handle _Atomic in the STL while permitting us to use _Atomic as a
keyword everywhere else.

more modules are added: visit modules depth-first rather than breadth-first.
The visitation is still (approximately) oldest-to-newest, and still guarantees
that a module is visited before anything it imports, so modules that are

Clang used to silently ignore __declspec(novtable). It is implemented
now, but leaving the vtable uninitialized does not work when using the
Itanium ABI, where the class layout for complex class hierarchies is
stored in the vtable. It might be possible to honor the novtable
attribute in some simple cases and either report an error or ignore
it in more complex situations, but it’s not clear if that would be
worthwhile. There is also value in having a simple and predictable
behavior, so this changes clang to simply ignore novtable when not using
the Microsoft C++ ABI.

We were still using the Unix response file tokenizer for all driver

This helps with freeform documentation styles, where otherwise code like
enum class E {
E1, // D1
E2 // D2
};
would result in D1 being associated with E2. To properly associate E1
with D1 and E2 with D2, this patch allows all raw comments C such that
C.isParseAllComments() to participate in trailing comment checks inside
getRawCommentForDeclNoCache. This takes care of linking the intended
documentation with the intended decls. There remains an issue with code
like:
foo(); // DN
int x;
To prevent DN from being associated with x, this patch adds a new test
on preceding-line comments C (where C.isParseAllComments() and also
C's kind is RCK_OrdinaryBCPL or RCK_OrdinaryC) that checks whether C
is the first non-whitespace thing on C's starting line.

MSVC 4.2 didn't have bool as a builtin type but MSVC 5.0 does. When

The vec_sld interface provides access to the vsldoi instruction.
Unlike most of the vec_* interfaces, we do not attempt to change the
generated code for vec_sld based on the endian mode. It is too
difficult to correctly infer the desired semantics because of
different element types, and the corrected instruction sequence is
expensive, involving loading a permute control vector and performing a
generalized permute.
For GCC, this was implemented as "Don't touch the vec_sld"
implementation. When it came time for the LLVM implementation, I did
the same thing. However, this was hasty and incorrect. In LLVM's
version of altivec.h, vec_sld was previously defined in terms of the
vec_perm interface. Because vec_perm semantics are adjusted for
little endian, this means that leaving vec_sld untouched causes it to
generate something different for LE than for BE. Not good.
This patch adjusts the form of vec_perm that is used for vec_sld and
vec_vsldoi, effectively undoing the modifications so that the same
vsldoi instruction will be generated for both BE and LE.
There is an accompanying back-end patch to take care of some small
ripple effects caused by these changes.
