This should automatically include it for those people who need it.

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).

* 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.

order, causing the inactive list in the linearscan list to get unsorted, which
basically fuxored everything up severely.

These seems to fix the joiner, so with more testing I will enable it by default.

is sorted.  This is not the case currently, which is causing no end of
problems.

Heavily refactor handleVirtualRegisterDef, adding comments and making it more
efficient.  It is also much easier to follow and convince ones self that it is
correct :)

Add -debug output to the joine, showing the result of joining the intervals.

break the important contract this library has with its user: LLVM.

night compiling cfrac.  It did not realize that code like this:

int G; int *H = &G;

takes the address of G.
