Hi Jeff,

Thanks a lot for verifying the patch and useful suggestions.

Yes, the peepholes cause the branch to be based on the output of bit.
However, the peepholes were implemented as they generate new
conditional bit instructions. We realize that they do not help in any 
optimization. Hence, peepholes will be removed as per the suggestion
and patch will be reposted when GCC returns to stage1.
