Zhongxing Xu 2c677c34d5 Finish the implementation of VisitCompoundLiteralExpr. As VisitInitListExpr is 
available, things get much simplified.

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

Dale Johannesen 7aad542d35 When we're doing a compare of load-AND-constant to 0 
(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).

Bill Wendling eb4268d72f - Modify the stack protector algorithm so that the stack slot is allocated in 
LLVM IR code and not in the selection DAG ISel. This is a cleaner solution.

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

Douglas Gregor 7d5fc7e28b Initial, rudimentary implementation of operator overloading for binary 
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.

Bill Wendling d939a7b305 The size limit is for individual arrays. So if any array has more than 8 bytes 
in it, then emit stack protectors.

Douglas Gregor 11d0c4c098 Parsing, ASTs, and semantic analysis for the declaration of overloaded 
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".

Bill Wendling d970ea3eac Implement the stack protector stack accesses via intrinsics: 
- stackprotector_prologue creates a stack object and stores the guard there.

- stackprotector_epilogue reads the stack guard from the stack position created
  by stackprotector_prologue.

- The PrologEpilogInserter was changed to make sure that the stack guard is
  first on the stack frame.
