9c2cc4626b Fix a bug: this does not preserve the CFG! 
While we're at it, add support for updating loop information correctly.

83bf2880c3 Initial checkin of a simple loop unroller. This pass is extremely basic and 
limited.  Even in it's extremely simple state (it can only *fully* unroll single
basic block loops that execute a constant number of times), it already helps improve
performance a LOT on some benchmarks, particularly with the native code generators.
