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).

Pull determination of the super region for a VarRegion into a single getVarRegion() method.  This provides a common clean API for clients.

 - 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.

Add setSubgraphColor to color an entire portion of a SelectionDAG.  This
will be used to support debug features in TableGen.

Add STL-style typedefs and default constructors to make it possible to
use DenseMap in more contexts.

Fix PR2634.  Create new virtual registers from spills early so that we
can give it the same stack slot as the spilled interval if it is folded.
This prevents the fold/unfold code from pointing to the wrong register.

(and a bunch of other node types).  While there, I
added a doNotCSE predicate and used it to reduce code
duplication (some of the duplicated code was wrong...).
This fixes ARM/cse-libcalls.ll when using LegalizeTypes.

worklist twice: UpdateNodeOperands could morph
a new node into a node already on the worklist.
We would then recalculate the NodeId for this
existing node and add it to the worklist.  The
testcase is ARM/cse-libcalls.ll, the problem
showing up once UpdateNodeOperands is taught to
do CSE for calls.

When destroying a translation unit, deallocate its owned declarations in reverse order, because there may be dependencies among the declarations.
