[PATCH] Move split-path pass next to the tracer pass

Richi noted that the two passes, which do very similar things are at 
slightly different places in the pipeline.  There really isn't a good 
reason for that.

This patch sinks the split-path pass slightly so that it's immediately 
before the tracer pass.


Bootstrapped and regression tested on x86_64-linux-gnu & installed on 
the trunk.
