2d86ea21dd Implement Value* tracking for loads and stores in the selection DAG. This enables one to use alias analysis in the backends.
(TRUNK)Stores and (EXT|ZEXT|SEXT)Loads have an extra SDOperand which is a SrcValueSDNode which contains the Value*.  Note that if the operation is introduced by the backend, it will still have the operand, but the value* will be null.

9696a90ee6 * store immediate values as int64_t, not int. come on, we should be happy
when there are immediates, let's not worry about the memory overhead of
this :)

* add addU64Imm(uint64_t val) to machineinstrbuilder

(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )

coming up next week: "all your floating point constants are belong to us"

72af57f26c Rewrite this class, making the following improvements:
1. It now actually uses tarjan's algorithm, so it is a efficient inverse
     ackerman's function for union operations, not linear time.
  2. It now stores one copy of the data in the set instead of two.
  3. It now works for elements other than pointers.
  4. It now has a more STL-like interface that exposes iterators instead
     of internal implementation details.
