One addition is that CompoundLiteralExpr can appear both in rvalue and lvalue
context.

(e.g. a bitfield test) narrow the load as much as possible.
The has the potential to avoid unnecessary partial-word
load-after-store conflicts, which cause stalls on several targets.
Also a size win on x86 (testb vs testl).

- Fix the heuristic for determining if protectors are necessary. The previous
  one wasn't checking the proper type size.

operators. For example, one can now write "x + y" where x or y is a
class or enumeration type, and Clang will perform overload resolution
for "+" based on the overloaded operators it finds.

The other kinds of overloadable operators in C++ will follow this same
approach. 

Three major issues remain:
  1) We don't find member operators
  2) Since we don't have user-defined conversion operators, we can't
  call any of the built-in overloaded operators in C++ [over.built].
  3) Once we've done the semantic checks, we drop the overloaded
  operator on the floor; it doesn't get into the AST at all.

operators in C++. Overloaded operators can be called directly via
their operator-function-ids, e.g., "operator+(foo, bar)", but we don't
yet implement the semantics of operator overloading to handle, e.g.,
"foo + bar".
