bee7e7644b Rewrite cast->cast elimination code completely based on the information we 
actually care about.  Someday when the cast instruction is gone, we can do
better here, but this will do for now.  This implements
instcombine/cast.ll:test17/18 as well.

7ed43ad3ab Added support for stdint.h. It is now automatically included by 
DataTypes.h.  So far, it doesn't seem to break Linux, Solaris, or MacOS X.
This should automatically include it for those people who need it.

cc0d156f7b When joining intervals, join intervals in deeply nested loops first. This 
is a simple change, but seems to improve code a little.  For example, on
256.bzip2, we went from 75.0s -> 73.33s (2% speedup).

8ea13c6233 Two changes, both very significant: 
* vreg <-> vreg joining now works, enable it unconditionally when joining
  is enabled (which is the default).
* Fix a serious pessimization of spill code where we were saying that a
  spilled DEF operand was live into the subsequent instruction.  This allows
  for substantially better code when spilling starts to happen.
