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

  - 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.

Only loc::MemRegionVal can be modified. This avoids crashing in RegionStore when a function pointer is used as an argument.

Simplify ArrayToPointer conversion. Actually the only thing we need to do is to get the first element region. It is not necessary to care about the kind of the base array region.

Implicit conversions from arrays can also be conversions to references (will add a test case shortly).

Issue warnings about owned objects returned from a method that does not match the established Cocoa naming conventions.

Added method "getSelfRegion" to Store.  This method returns the region associated with the "this" or "self" object (C++ and Objective-C respectively).

Disable warning about potential leaks of returned values until we test it a little more (lots of noise).
