Update branch coalescing to be a PowerPC specific pass
Implementing this pass as a PowerPC specific pass. Branch coalescing utilizes
the analyzeBranch method which currently does not include any implicit operands.
This is not an issue on PPC but must be handled on other targets.
Pass is currently off by default. Enabled via -enable-ppc-branch-coalesce.
