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.

(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.

Fix two bugs:
...
* The globals vector was getting broken and unsorted, this caused vortex
to get badly pessimized
* Node offset handling was being handled really poorly, and in particular
we were not merging types with offsets right. This causes several graphs
to be non-merged.
