[PowerPC] Add predicted forms of branches
This adds support for the predicted forms of branches (+/-). There are three cases to consider: - Branches using a PPC::Predicate code For these, I've added new PPC::Predicate codes corresponding to the BO values for predicted branch forms, and updated insn printing to print them correctly. I've also added new aliases for the asm parser matching the new forms. - bt/bf I've added new aliases matching to gBC etc. - bd(n)z variants I've added new instruction patterns for the predicted forms. In all cases, the new patterns are used for the asm parser only. (The new infrastructure ought to be sufficient to allow use by the compiler too at some point.) llvm-svn: 184754
