Eliminate duplicate code in Cmm pipeline
Eliminate duplicate code in Cmm pipeline

End of Cmm pipeline used to be split into two alternative flows,
depending on whether we did proc-point splitting or not. There
was a lot of code duplication between these two branches. But it
wasn't really necessary as the differences can be easily enclosed
within an if-then-else. I observed no impact of this change on
compilation performance.
