 Add ISel::visitShiftInst() to instruction select shift instructions.
 Add a comment in visitAdd about how to do 64 bit adds.

X86InstrInfo.def: Add register-to-register move opcodes and shift opcodes.

Huge thanks go to Casey Carter for writing this fix, reassociate is now

because this is usually such a long list that it makes the output
useless anyway.

Disable checking exit status until we can find something more precise.
The exit status is too coarse-grain to be useful.

* DSGraph.h   contains DSGraph
* DSNode.h    contains DSNode (soon UDSNode and MDSNode)
* DSSupport.h contains DSCallsite, DSTypeRec, and DSNodeHandler

be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

  * Load Implementation can cause unaligned memory accesses, which caused
    problems for sparc.
  * cast from pointer to pointer would zero the upper 32 bits of the pointer
    which obviously causes problems on 64 bit hosts.
