Douglas Gregor 85f240c788 Implement the rvalue-reference deduction transformation (from T&& ->
T) when taking the address of an overloaded function or matching a
specialization to a template (C++0x [temp.deduct.type]p10). Fixes
PR9044.

Douglas Gregor 912e161ce0 An rvalue reference cannot bind to an lvalue, so static_cast the
result of the __tuple_leaf::get() call to an rvalue reference when
returning from tuple's get().

Duncan Sands d395108394 According to my auto-simplifier the most common missed simplifications in
optimized code are:
  (non-negative number)+(power-of-two) != 0 -> true
and
  (x | 1) != 0 -> true
Instcombine knows about the second one of course, but only does it if X|1
has only one use.  These fire thousands of times in the testsuite.

Greg Clayton 4cd178020c Fixed an issue that was stopping LLDB from finding complete definitions for
types. What was happening was the DWARF parser was almost ignoring definitions
(DIEs with the DW_AT_declaration set to 1). It wasn't ignoring declarations
that had _some_ children. When this happened, we would treat the declaration
as a complete type. Often we would have a declaration of a type with just
some enum definitions inside and nothing else. Now we correctly ignore these
definitions, and also I added some changes to allow us to figure out what
decl context these special declarations actually point to.

Douglas Gregor a7b2241407 Eliminate the C++0x-only is_convertible testing function that accepts
a cv-qualifier rvalue reference to the type, e.g.,

  template <class _Tp> char  __test(const volatile typename remove_reference<_Tp>::type&&);

The use of this function signature rather than the more
straightforward one used in C++98/03 mode, e.g.,

  template <class _Tp> char  __test(_Tp);

is broken in two ways:

  1) An rvalue reference cannot bind to lvalues, so is_convertible<X&,
  X&>::value would be false. This breaks two of the unique_ptr tests
  on Clang and GCC >= 4.5. Prior GCC's seem to have allowed rvalue
  references to bind to lvalues, allowing this bug to slip in.

  2) By adding cv-qualifiers to the type we're converting to, we get
  some incorrect "true" results for, e.g., is_convertible<const X&, X&>::value.

Argyrios Kyrtzidis ffb08c46fa [analyzer] Handle the dot syntax for properties in the ExprEngine.
We translate property accesses to obj-c messages by simulating "loads" or "stores" to properties
using a pseudo-location SVal kind (ObjCPropRef).

Checkers can now reason about obj-c messages for both explicit message expressions and implicit
messages due to property accesses.
