where the control reaches the end of a non-void function and also allows the
compiler to generate better code.  When this assertion is false we can easily
add more else cases.

C++ constructors, destructors, and conversion functions now have a
FETokenInfo field that IdentifierResolver can access, so that these
special names are handled just like ordinary identifiers. A few other
Sema routines now use DeclarationNames instead of IdentifierInfo*'s.

To validate this design, this code also implements parsing and
semantic analysis for id-expressions that name conversion functions,
e.g.,

  return operator bool();

The new parser action ActOnConversionFunctionExpr takes the result of
parsing "operator type-id" and turning it into an expression, using
the IdentifierResolver with the DeclarationName of the conversion
function. ActOnDeclarator pushes those conversion function names into
scope so that the IdentifierResolver can find them, of course.

are trying to use the old GCC "casts as lvalue" extension.  We don't and
will hopefully never support this.

languages. DeclarationName is used in NamedDecl to store the name of
the declaration (naturally), and ObjCMethodDecl is now a NamedDecl.

 - RegionView and RegionViewMap is introduced to assist back-mapping from
   super region to subregions.
 - GDM is used to carry RegionView information.
 - AnonTypedRegion is added to represent a typed region introduced by pointer
   casting. Later AnonTypedRegion can be used in other similar cases, e.g.,
   malloc()'ed region.
 - The specific conversion is delegated to store manager.
