The register constraint could mean a 16- or 8-bit register.

Per discussion on cfe-dev, re-enable suppression of -Wimplicit-fallthrough on C, but also include dialects of C++ earlier than C++11.

There was enough consensus that we *can* get a good language solution
to have an annotation outside of C++11, and without this annotation
this warning doesn't quite mean's completeness criteria for this
kind of warning.  For now, restrict this warning to C++11 (where an
annotation exists), and make this the behavior for the LLVM 3.2 release.
Afterwards, we will hammer out a language solution that we are all
happy with.

If we encounter a fatal error, exit with status 70.  For BSD systems this is
defined as an internal software error.  This notifies the driver to report
diagnostics information.

internal linkage, no uses, trivial construction, and nontrivial destruction
were not emitted.

[analyzer] Fix a regression (from r 165079): compare canonical types.

Suppresses a leak false positive (radar://12663777).

In addition, we'll need to rewrite the adjustReturnValue() method not to
return UnknownVal by default, but rather assert in cases we cannot
handle. To make it possible, we need to correctly handle some of the
edge cases we already know about.

Fix more try scoping bugs introduced by r167650.

Introduces more clear scoping flags & flag combinations which should hopefully
be more understandable.

Factor duplicated implicit memcpy call generation code out of copy/move
assignment generation. This incidentally avoids reusing the same Expr* across
multiple statements in the same object; that was generating slightly broken
ASTs, but I couldn't trigger any observable bad behavior, so no test.

[analyzer] Follow up to r167762 - precisely determine the adjustment
conditions.

The adjustment is needed only in case of dynamic dispatch performed by
the analyzer - when the runtime declaration is different from the static
one.

Document this explicitly in the code (by adding a helper). Also, use
canonical Decls to avoid matching against the case where the definition
is different from found declaration.

This fix suppresses the testcase I added in r167762, so add another
testcase to make sure we do test commit r167762.

Enable C++11 attribute syntax for warn_unused_result and allow it to be
applied to CXXRecordDecls, where functions with that return type will
inherit the warn_unused_result attribute.

Also includes a tiny fix (with no discernable behavior change for
existing code) to re-sync AttributeDeclKind enum and
err_attribute_wrong_decl_type with warn_attribute_wrong_decl_type since
the enum is used with both diagnostic messages to chose the correct
description.

When filtering the list of associated namespaces so that we don't suggest people
add functions to namespace 'std', also filter out namespaces with '__' anywhere
in the name.

Fix bad CFG construction bug when handling C++ 'try' statements.

This code assigned the last created CFGBlock* to the variable 'Block',
which is a scratch variable which is null'ed out after a block is
completed.  By assigning the last created block to 'Block', we start
editing a completed block, inserting CFGStmts that should be in
another block.  This was the case with 'try'.  The test case that
showed this had a while loop inside a 'try', and the logic before
the while loop was being included as part of the "condition block"
for the loop.  This showed up as a bogus dead store, but could
have lots of implications.

Turns out this bug was replicated a few times within CFG.cpp, so
I went and fixed up those as well.
