mismatches if when linking an internal foo to an external foo.

pointer cast hack currently in isIntegerConstantExpr 
(in lib/AST/Expr.cpp).  Also removes an odd test that even gcc doesn't accept.

The reason the pointer cast hack is relevant here is that it makes Sema 
end up misinterpreting the relevant expression as a null pointer constant.

The reason for this patch is that I plan to remove the pointer cast hack 
sometime soon because it causes strange issues, especially in its 
current form; see my recent email to cfe-dev
"[PATCH] add constant expression evaluation to the AST and fix PR2413".

of apint codegen failure is the DAG combiner doing
the wrong thing because it was comparing MVT's using
< rather than comparing the number of bits.  Removing
the < method makes this mistake impossible to commit.
Instead, add helper methods for comparing bits and use
them.
