"previous token" location at the end of the class definition. This
eliminates a badly-placed error + Fix-It when the ';' following a
class definition is missing. Fixes <rdar://problem/8066414>.

introduced by using decls are hidden even if their template parameter lists
or return types differ from the "overriding" declaration.
Propagate using shadow declarations around more effectively when looking up
template-ids. Reperform lookup for template-ids in member expressions so that
access control is properly set up.
Fix some number of latent bugs involving template-ids with totally invalid
base types. You can only actually get these with a scope specifier, since
otherwise the template-id won't parse as a template-id.
Fixes PR7384.

C++ semantics, eliminating an extension diagnostic that doesn't match
C++ semantics (ordered comparison with NULL) and tightening some
extwarns to errors in C++ to match GCC and maintain conformance in
SFINAE contexts. Fixes <rdar://problem/7941392>.

Fix string concatenation to treat escapes in concatenated strings that
are wide because of other string chunks to process the escapes as wide
themselves. Before we would warn about and miscompile the attached testcase.
This fixes rdar://8040728 - miscompile + warning: hex escape sequence out of range

the first 4 overloads, but we'll improve that over time.

being a subsequence of another standard conversion sequence. Instead
of requiring exact type equality for the second conversion step,
require type *similarity*, which is type equality with cv-qualifiers
removed at all levels. This appears to match the behavior of EDG and
VC++ (albeit not GCC), and feels more intuitive. Big thanks to John
for the line of reasoning that supports this change: since
cv-qualifiers are orthogonal to the second conversion step, we should
ignore them in the type comparison.

VLA restrictions so that one can use VLAs in templates (even
accidentally), but not as part of a non-type template parameter (which
would be very bad).

in several important ways:
- VLAs of non-POD types are not permitted.
- VLAs cannot be used in conjunction with C++ templates.
These restrictions are intended to keep VLAs out of the parts of the
C++ type system where they cause the most trouble. Fixes PR5678 and
<rdar://problem/8013618>.

CXXBasePaths::isAmbiguous(), rather than just asserting that we have a
canonical type. Fixes PR7176.

instance variables:
- Use isRecordType() rather than isa<RecordType>(), so that we see
through typedefs in ivar types.
- Mark the destructor as referenced
- Perform C++ access control on the destructor

the Boost.Interprocess failures.
Daniel did all the hard work of tracking down the issue, I get to type
up the trivial fix for this horrible miscompile.

If a switch condition is constant, warn if there's no case for it.
Constant switch conditions do come up in reasonable template code.
