- Checkin of the alias analysis work:
...
* Takes into account the size of the memory reference to determine aliasing.
* Expose mod/ref information in a more consistent way
* BasicAA can now disambiguate A[i][1] and A[j][2] for conservative request

This is a substantial rewrite of the AliasSetTracker class which now uses
...
a union-find based algorithm, is significantly faster, and is more general.
It will also scale to handle call instructions correctly, which is a nice
added bonus.
This includes a new pass -print-alias-sets which can be used to show how
alias sets are formed for a particular analysis.

moria: .6756 3150 .7054 3877
300.twolf: .1652 2010 .1851 3270
Typically, testcases which use long and ulong integers a lot get better, f.e. povray above.

This file implements a pass that automatically parallelizes a program,
...
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.

fact that the incoming nodes may be merged away at intermediate

(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.
