Add the annotations and code needed to support a basic 'consumed' analysis.
Summary:
This new analysis is based on academic literature on linear types. It tracks
the state of a value, either as unconsumed, consumed, or unknown. Methods are
then annotated as CallableWhenUnconsumed, and when an annotated method is
called while the value is in the 'consumed' state a warning is issued. A value
may be tested in the conditional statement of an if-statement; when this occurs
we know the state of the value in the different branches, and this information
is added to our analysis. The code is still highly experimental, and the names
of annotations or the algorithm may be subject to change.

SourceRange should include any existing nested name specifier even if
the candidate isn't adding a different one (i.e. the candidate has a
NULL NestedNameSpecifier).

that just replaces the identifer but leaves the existing nested name
specifier intact and one that replaces the entire qualified identifier,

like warning on the divisor in this code:

Introduce CXXStdInitializerListExpr node, representing the implicit

The AST representation of such an expression goes from an InitListExpr with a

containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr).
This more detailed representation has several advantages, the most important of
which is that the new MaterializeTemporaryExpr allows us to directly model
lifetime extension of the underlying temporary array. Using that, this patch
*drastically* simplifies the IR generation of this construct, provides IR
generation support for nested global initializer_list objects, fixes several
bugs where the destructors for the underlying array would accidentally not get
invoked, and provides constant expression evaluation support for

While the C++ standard requires that this lookup take place only at the
definition point of a virtual destructor (C++11 [class.dtor]p12), the
Microsoft ABI may require the compiler to emit a deleting destructor
for any virtual destructor declared in the TU, including ones without
a body, requiring an operator delete() lookup for every virtual
destructor declaration. The result of the lookup should be the same
no matter which declaration is used (except in weird corner cases).
This change will cause us to reject some valid TUs in Microsoft ABI
mode, e.g.:
struct A {
void operator delete(void *);
};
struct B {
void operator delete(void *);
};
struct C : A, B {
virtual ~C();
};
As Richard points out, every virtual function declared in a TU
(including this virtual destructor) is odr-used, so it must be defined
in any program which declares it, or the program is ill formed, no
diagnostic required. Because we know that any definition of this
destructor will cause the lookup to fail, the compiler can choose to
issue a diagnostic here.

selectany only applies to externally visible global variables. It has

The MSDN docs suggest that unused definitions can only be dropped at

wchar_t s[] = "Hi";
^
/tmp/a.c:4:6: error: initializing char array with wide string literal

^
As a bonus, it also fixes the fact that Clang would previously reject
this valid C11 code:
char16_t s[] = u"hi";

because it would only recognize the built-in types for char16_t and
