Fix logical error in TD pass: we should clear Mod/Ref bits of each caller
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

Added flags to CloneFlags to strip/keep Mod/Ref bits when cloning a graph.

No longer need local graph to find call sites.
Also some major fixes within IPModRef.cpp.

(1) Bug fix that was causing nodes with dangling references to be freed.
    We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

Oops. Got the MOVrm and MOVmr mixed up. Fixed. We can now print out
instructions correctly.
