(u)intval, because latter are not
present in older caml/mlvalues.h
(e.g. 2004/07/07, 1.48.6.1)

Using this as a workaround for now,
until --without-ocaml works
or we settle on a better solution

returned a reference type.  This patch allows operator*() to return a
non-reference type while still maintaining the old behavior when it
does return a reference type.

This patch was motivated when I tried to use "df_iterator" (see
llvm/ADT/DepthFirstIterator.h) as a "node_iterator", as df_iterator
does not return a reference type and thus we would get a compilation
error when trying to take the address of a temporary.

Moved GraphTraits<Stmt*> to StmtGraphTraits.h.  This allows consumers of Stmt.h not to have to pay the cost
of parsing the GraphTraits templates if they don't need that functionality.

Defined nodes_iterator for GraphTraits<Stmt*> to be based on llvm::df_iterator.

The extended functionality of these visitors is that they automatically visit all statements in
an AST (no explicit recursion is required from subclasses), and the for the latter, decls are visited
as well.

Remove SelectorTable/SelectorInfo, simply store all selectors in the central IdentifierTable.

Rationale:

We currently have a separate table to unique ObjC selectors. Since I don't need all the instance data in IdentifierInfo, I thought this would save space (and make more sense conceptually).

It turns out the cost of having duplicate entries for unary selectors (i.e. names without colons) outweighs the cost difference between the IdentifierInfo & SelectorInfo structures. Here is the data:

Two tables:

*** Selector/Identifier Stats:
# Selectors/Identifiers: 51635 
Bytes allocated:         1999824

One table:

*** Identifier Table Stats:
# Identifiers:   49500
Bytes allocated: 1990316
