John McCall 622114cfe3 Clarify the logic for when to build an overloaded binop. In particular,
build one when either of the operands calls itself type-dependent;
previously we were building when one of the operand types was dependent,
which is not always the same thing and which can lead to unfortunate
inconsistencies later.  Fixes PR8739.

Francois Pichet d583da04d0 More anonymous struct/union redesign. This one deals with anonymous field used in a constructor initializer list:
struct X {
  X() : au_i1(123) {}
  union {
    int au_i1;
    float au_f1;
  };
};

clang will now deal with au_i1 explicitly as an IndirectFieldDecl.

John McCall 29cb2fdbc1 When deciding whether to complain about the type of a boolean condition, use
the type of the expression *after* array/function decay.

John McCall 34376a68c4 Although we currently have explicit lvalue-to-rvalue conversions, they're
not actually frequently used, because ImpCastExprToType only creates a node
if the types differ.  So explicitly create an ICE in the lvalue-to-rvalue
conversion code in DefaultFunctionArrayLvalueConversion() as well as several
other new places, and consistently deal with the consequences throughout the
compiler.

In addition, introduce a new cast kind for loading an ObjCProperty l-value,
and make sure we emit those nodes whenever an ObjCProperty l-value appears
that's not on the LHS of an assignment operator.

This breaks a couple of rewriter tests, which I've x-failed until future
development occurs on the rewriter.

Ted Kremenek kindly contributed the analyzer workarounds in this patch.

Douglas Gregor 8d6d06761f Improve our handling of cv-qualifiers in Objective-C pointer
conversions. Previously, we would end up collapsing qualification
conversions into the Objective-C pointer conversion step, including
(possibly) stripping qualifiers that shouldn't be removed.

This generalizes BuildSimilarlyQualifiedPointerType() to also work on
Objective-C object pointers, then eliminates the (redundant, not
totally correct) BuildSimilarlyQualifiedObjCObjectPointerType()
function.

Fixes <rdar://problem/8714395>.

Nick Lewycky ef4f456866 Tie DefineVTablesUsed() in with recursive function instantiation so that we emit

This also causes a slight change to where the "instantianted from" note shows up
in truly esoteric cases (see the change to test/SemaCXX/destructor.cpp), but
that isn't directly the fault of this patch.

John McCall feb624a435 A few tweaks to the value-kind computation:
- Default argument expressions pick up the value kind of the incoming
   expression, not the value kind of the parameter it initializes.
 - When building a template argument for substitution, A::x is an rvalue
   if x is an instance method.
 - Anonymous struct/union paths pick up value kind the same way that
   normal member accesses do;  extract out a common code path for this.

Enable the value-kind assertion, now that it passes self-host.
