<pre>Currently, if an opcode is a branch type opcode. BytecodeBasicBlock::computeImpl() will iterate over all basic blocks looking for the block containing the jump target, and it will continue to do this even when all the jump targets have been found. This is wasted work, and all the more so given that most branch type opcodes only have a single jump target.</pre>
