AnalyzeBranch - Analyze the branching code at the end of MBB, returning true if it cannot be understood (e.g. it's a switch dispatch or isn't implemented for a target). Upon success, this returns false and returns with the following information in various cases:
1. If this block ends with no branches (it just falls through to its succ) just return false, leaving TBB/FBB null. 2. If this block ends with only an unconditional branch, it sets TBB to be the destination block. 3. If this block ends with an conditional branch and it falls through to an successor block, it sets TBB to be the branch destination block and a list of operands that evaluate the condition. These operands can be passed to other TargetInstrInfo methods to create new branches. 4. If this block ends with an conditional branch and an unconditional block, it returns the 'true' destination in TBB, the 'false' destination in FBB, and a list of operands that evaluate the condition. These operands can be passed to other TargetInstrInfo methods to create new branches.
Note that RemoveBranch and InsertBranch must be implemented to support cases where this method returns success.
