you would walk off the end of the FloatCCRegName array.

Remove the extra %fsr register from SparcV9FloatCCRegClass.

wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of
special-casing by class of user.

* Remove #include
* Add some methods to update loop/loopinfo
* Stop explicitly holding the loop depth in the Loop class.  Instead, just
  dynamically calculate it.  This makes it easier to update LoopInfo as a
  result of transformations.

by creating an internal wrapper function with same signature as the external
function, and use it instead of the "real" function.

The wrapper then calls the external function using the same JIT function
resolution API that has been used before for rewriting instructions, since the
wrapper has an explicit call instruction which we can rewrite.
