The background of the problems is as follows:
1 Current iterator current Frame, visit previous Frame stackmap, it's hard to understand.
2 refactor llvm_stackmap_parser
3 refactor frameHandler， we should provider iterator to visit frame.
The solution of the problems is as follows:
1 FrameHandler Ietrator only visit current Frame stackmap
2 In the future, multiple vm may be existed such as multiple worker.while llvm_stackmap_parser is singleton which is not good, each vm should have one stackmap.
3. refactor frame add FrameIterator to visit frame
