296c58a00c - Make sure to only keep track of mappings that the TD pass may need in the
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

4410178282 - Add "ResolvingCaller" to the CallSite record. This keeps track of which
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

1276c50e7b As it turns out, we don't need a fully generic mapping copy ctor, we just need
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

2914391ab6 - Make DSCallSite not inherit from std::vector. Renamed methods slightly.
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

c02c96c3de Added a first-class representation for each call site that can be
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.

fb6bb789a1 * Add capability to recognize alias properties of the following common cases:
- A[c1] cannot alias A[c2] where constants c1 != c2
  - A[i] cannot alias B[j] if A & B are provably different arrays

This should help out array based codes.  For example, from bzip2 from spec,
3 additional loads can be GCSE'd, and _21_ additional loads can be LICMd due
to this change.

In a test example from the Spec GAP benchmark (vecffe.c), this change allows
_52_ additional loads to be GCSE'd and _224_ additional LICM'd loads.

Not bad for such a simple change.  Other testcases show no change at all
because they just don't use arrays.  Not too suprising there.
