Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned
...
out that almost always the result of the add was the same as the GEP that
would be generated. In this case, however, it wasn't, so bad things happened.

// Peephole optimize the following instructions:

// %t1 = cast <eltype> * %t1 to <ty> *
This peephole eliminated 9 evil casts in the health benchmark, and
completely turned the addList method around. :)
