> This patch refactors the `StackMapReader` to clean up the `StackMapTable` constructor. The `StackMapReader` class is extended to hold more fields used for verification purposes and allows for a simpler StackMapTable constructor. Additionally, in preparation for further changes to verification, the `_frame_count` may not be equal to the value reported by the classfile, so a new structure is used to generate the `_frame_array`. Verified with tier 1-5 tests
