final ternary expression value from).

Rather than adding a ContainsUnexpandedParameterPack bit to essentially every
AST node, we tunnel the bit directly up to the surrounding lambda expression
when we reach a context where an unexpanded pack can not normally appear.
Thus any statement or declaration within a lambda can now potentially contain
an unexpanded parameter pack.

This tests for the ability to include a "message" field in availability
attributes, like so:
extern void ATSFontGetName(const char *oName)
__attribute__((availability(macosx,introduced=8.0,deprecated=9.0,
message="use CTFontCopyFullName")));
This was actually supported in Clang 3.1, but we got a request for a
__has_feature so that header files can use this more safely. It's
unfortunate that the 3.1 release doesn't include this, however.

A warning was added in r150128 for returning non-C compatible
user-defined types from functions with C linkage.
This makes the text more clear for the case when the type isn't
decidedly non-C compatible, but incomplete.

as per Chandler's request:
- introduces a new matcher base type BindableMatcher that
provides the bind() call
- makes all dynamic-cast matcher creation functions return
BindableMatchers; the special case about dynamic-cast
matchers is that the node they match on and the node
their child matchers match on are the same node, just
casted to a different type; thus, there is no ambiguity
on what bind() matches on; additionally, those are the
matchers that we name with nouns in the matcher language,
so it's easy for users to intuitively know which matchers
are bindable
To make this change possible, we got rid of a non-orthogonal
implementation of thisPointerType, which had an implicit
dynamic-cast matcher from CallExpr to CXXMemberCallExpr; as
alternative, we now provide a memberCall dynamic-cast matcher
and thisPointerType is a predicate on CXXMemberCallExpr.
Last, the ArgumentAdaptingMatcher is actually not required
for the implementation of makeDynCastAllOfComposite - this
simplification makes it more obvious where the bind() call
can be used based on the matcher creation function types.

1) In a template instantiation, the context declaration should be the

2) If a lambda appears in the pattern of a variadic pack expansion, the
mangling number will depend on the pack length.

By default, we don't emit IR for MS-style inline assembly (see r158833 as to
why). This is strictly for testing purposes and should not be enabled with the
expectation that things will work. This is a temporary flag and will be removed
once MS-style inline assembly is fully supported.

While we still want to consider this a hard error (non-POD variadic args are
normally a DefaultError warning), delaying the diagnostic allows us to give
better error messages, which also match the usual non-POD errors more closely.
In addition, this change improves the diagnostic messages for format string
argument type mismatches by passing down the type of the callee, so we can
say "variadic method" or "variadic function" appropriately.

The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option
in place of -mios-simulator-version-min leaves the Darwin version
unspecified. It can be set separately with -mmacosx-version-min (which
makes no sense) or inferred to match the host version (which is unpredictable
and usually wrong). This really needs to get cleaned up, but in the
meantime, force the OS X version to 10.6 so that the behavior is sane for
the iOS simulator. Thanks for Argyrios for the patch.
