RFR: 8308842: Consolidate exceptions thrown from Class-File API

[Adam Sotona]

Class-File API actually throws wide variety of exceptions based on the actual situation. Complete error handling code must cover `IndexOutOfBoundsException`, `IllegalStateException` and `IllegalArgumentException`. 

Based on previous discussions we decided to consolidate on `IllegalArgumentException` with possible sub-classes. 

It allows easy common error handling in majority of use case, however it allows also to distinguish source of the error when needed (for example `javap` needs to know if the exception comes from constant poll or not). 

Newly introduced `ConstantPoolException` extends `IllegalArgumentException` to indicate the source of the problem is in constant pool. 

Please review.

Thanks,
Adam
