Correctly classify T{} as an array temporary if T is an array of class type with nontrivial destructor.

Add a warning for when an array-to-pointer decay is performed on an array
temporary or an array subobject of a class temporary, and the resulting value
is used to initialize a pointer which outlives the temporary. Such a pointer
is always left dangling after the initialization completes and the array's
lifetime ends.
In order to detect this situation, this change also adds an
LValueClassification of LV_ArrayTemporary for temporaries of array type which
aren't subobjects of class temporaries. These occur in C++11 T{...} and GNU C++
(T){...} expressions, when T is an array type. Previously we treated the former
as a generic prvalue and the latter as a class temporary.

Follow through references to catch returned stack addresses, local blocks, label addresses or references to temporaries, e.g:
const int& g2() {
int s1;
int &s2 = s1; // expected-note {{binding reference variable 's2' here}}
return s2; // expected-warning {{reference to stack memory associated with local variable 's1' returned}}
}

Introduce a new kind of failed result for isLvalue/isModifiableLvalue
which describes temporary objects of class type in C++. Use this to
provide a more-specific, remappable diagnostic when takin the address
of such a temporary.
