Implement Value* tracking for loads and stores in the selection DAG.  This enables one to use alias analysis in the backends.

(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.

printf format strings and other stuff.  Instead of generating this:

        movl $l1__2E_str_1, %eax
        movl %eax, (%esp)

we now emit:

        movl $l1__2E_str_1, (%esp)
