a memset using 16-byte XMM stores, but where the stack realignment code
didn't work.  Until it does (PR2962) disable use of xmm regs in memcpy
and memset formation for linux and other targets with insufficiently
aligned stacks.

This is part of PR2888

  - 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.

- 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).
