Kang Zhang 65fe71d3b0 [PowerPC] Fix the implicit operands in PredicateInstruction()
Summary:
In the function `PPCInstrInfo::PredicateInstruction()`, we will replace
non-Predicate Instructions to Predicate Instruction. But we forget add
the new implicit operands the new Predicate Instruction needed. This
patch is to fix this.
