RFR: 8325485: IncrementInstructions.of(int, int) is not storing the args

[Adam Sotona]

ClassFile API provides two sets of instructions implementations (bound and unbound).
Unbound implementation of `IncrementInstruction::constant` returns invalid value. 
This bug discovered a hole in the ClassFile API test coverage.

This patch provides very simple fix of `IncrementInstruction`
and more complex fix of the test framework to cover all unbound instruction with automated tests.

The test framework fix includes correction of hash calculation of instructions in `ClassRecord` and
two-pass transformation in `RebuildingTransformation`. Second pass has been added to discover bugs in unbound-to-unbound instruction conversions.

Please review.

Thanks,
Adam
