8eb8eeada9 Insert new pre-header before new header. Original pre-header may 
happen to be an entry, in such case, it is not a good idea to
insert new block before entry.

Also fix typo in assertion check.

ce38beb6a4 For PR1146: 
* Add ParamAttrs to InvokeInst class too.
* Make sure all initializes of ParamAttrs in CallInst and InvokeInst are 0
* Destruct the ParamAttrs in Call/Invoke destructors to avoid memory
  leaks. This will change when ParamAttrsList is uniquified but needs to
  be correct until then.

506eaf7915 Next stage into switch lowering refactoring 
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.
