Recognize Bi as an indirect branch, just like Br and Bm. This allows
machine verification to run after MSP430BranchSelector without failing
this assertion:
virtual bool llvm::MSP430InstrInfo::analyzeBranch(llvm::MachineBasicBlock &, llvm::MachineBasicBlock *&, llvm::MachineBasicBlock *&, SmallVectorImpl<llvm::MachineOperand> &, bool) const: Assertion `I->getOpcode() == MSP430::JCC && "Invalid conditional branch"' failed.
Note that machine verification is currently disabled after
addPreEmitPass passes because of problems on other targets, so this is
currently NFC.
