* Add comments for peepholes
* Implement new peephole:
// Peephole optimize the following instructions:
// %t1 = cast {<...>} * %StructPtr to <ty> *
//
// Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
// %t1 = cast <eltype> * %t1 to <ty> *
This peephole eliminated 9 evil casts in the health benchmark, and
completely turned the addList method around. :)
