877ad7d80b Add a bunch of new functionality, primarily to do with removing aliasing
pointers from an AST.

12c1155403 Make the AST interface a bit richer by returning whether an insertion caused
an insertion or not (because the pointer set already existed).

e8a7e593e6 Remove special casing of pointers and treat them generically as integers of
the appopriate size.  This gives us the ability to eliminate int -> ptr -> int

bb8f43c8fc Do not ignore casts unless they are pointer-pointer casts. This caused us
to miscompile the SingleSource/Regression/C++/pointer_member.cpp program.

bee7e7644b Rewrite cast->cast elimination code completely based on the information we
actually care about.  Someday when the cast instruction is gone, we can do
better here, but this will do for now.  This implements
instcombine/cast.ll:test17/18 as well.
