cd2ae40679 gcroot must take concrete types, not arbitrary types. 
clean up intrinsic descriptions in langref a bit.

d65f36fb5d use typenames equivalent to 
(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

c924fd3edf Previously GraphWriter assumed operator*() for node_iterator always 
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.

dd6fc40100 Partial fix for PR1678: correct some parts of constant 
fold that were missed in the fix for PR1646.  Probably
this null/not-null logic should be factorized somewhere.
