Thomas Wuerthinger implemented a limited form of loop invariant code  
motion as part of the array bounds check elimination work. It is part  
of the global value numbering and optimized all the loops that the  
current global value numbering also optimizes, i.e., call-free blocks  
with a maximum length of a few basic blocks.
