Add support for a top-down propagation pass.
...
Each DSGraph now keeps a list of pending callers that have not
been inlined into the function represented by that graph.
It also keeps a copy of the original call nodes before the BU pass
eliminates some of them.

constants using operators such as cast, getelementptr, add, shl, etc.

so don't make that argument const!
