  - Do not allow expressions to ever have reference type
  - Extend Expr::isLvalue to handle more cases where having written a
    reference into the source implies that the expression is an lvalue
    (e.g., function calls, C++ casts).
  - Make GRExprEngine::VisitCall treat the call arguments as lvalues when
    they are being bound to a reference parameter.

Initialize Suffix and Prefix to 0, even with a bad entry.  Removes an uninitialized value warning from gcc.

  - Can be fixed once we implement C99 inline semantics.

- Add symbol_iterator support for SymbolicRegions.

- Add VERBOSE=1 flag.
- Specify the LLVM_SUBMIT_VERSION when doing the "make install".
  The libLTO.dylib relies upon this flag during that time.

Have TableGen emit setSubgraphColor calls under control of a -gen-debug
flag.  Then in a debugger developers can set breakpoints at these calls
to see waht is about to be selected and what the resulting subgraph
looks like.  This really helps when debugging instruction selection.

- GRExprEngine::VisitCompoundLiteral...
   (1) visits the initializer list (generating ExplodedNodes)
   (2) creates a CompoundMemRegion for the literal
   (3) creates a new state with the bound literal values using
       GRStateManager::BindCompoundLiteral

- GRStateManager::BindCompoundLiteral simply calls 
  StoreManager::BindCompoundLiteral to get a new store and returns a persistent
  GRState with that store.

- BasicStore::BindCompoundLiteral simply returns the same store, as it
  doesn't handle field sensitivity
  
- RegionStore::BindCompoundLiteral currently fires an assert (pending discussion
  of how to best implement mappings for CompoundLiteralRegion).

 - Add support for -MP (phony targets).
 
 - Use raw_ostream for output instead of std::string concatenation.
 
 - Break long lines in a GCC (4.2) compatible manner.

 - Output dependents in #included order (to match GCC).

  - CastExpr is the root of all casts
  - ImplicitCastExpr is (still) used for all explicit casts
  - ExplicitCastExpr is now the root of all *explicit* casts
  - ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++
  - CXXFunctionalCastExpr inherits from ExplicitCastExpr
  - CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all
    of the C++ named cast expression types (static_cast, dynamic_cast, etc.)
  - Added classes CXXStaticCastExpr, CXXDynamicCastExpr, 
    CXXReinterpretCastExpr, and CXXConstCastExpr to 

Also, fixed returned-stack-addr.cpp, which broke once when we fixed
reinterpret_cast to diagnose double->int* conversions and again when
we eliminated implicit conversions to reference types. The fix is in
both testcase and SemaChecking.cpp.

Most of this patch is simply support for the renaming. There's very
little actual change in semantics.

- Implement child_begin() and child_end() for AsmStmt.  Previously these had stub implementations that did not iterate over the input/output operands of an inline assembly statement.
- Use ExprIterator for performing iteration over input/output operands.
