[Bug rtl-optimization/36712] Inefficient loop unrolling

[bmei at broadcom dot com]

I only submitted small patch before. To add a pass (may need new command-line
option, disabling the old rtl-level unrolling) seems to be a big issue to me.
Don't know what's procedure. 

My code also contains my own implementation of #pragma unroll. I need to clean
it up for the public patch.
