Fix: Fix arrays of AtomicInteger stored on local variables no longer …

[CoreRasurae]

…fail with type cast exception - Partial fix for (refs #138)

Currently Aparapi fails with a type cast exception on Arrays that are used as local variables, this was verified with arrays of AtomicInteger, but could possibly happen with other types. Since not all array variables are stored on class instance fields, AccessField type bytecode instructions, the ones that were stored on local variables use different bytecode instruction (LocalVariableConstIndexAccessor) and a type cast exception was generated. This fix adds support for I_ALOAD, I_ALOAD_0, I_ALOAD_1, I_ALOAD_2 and I_ALOAD_3 bytecode instructions which are used when arrays are stored as local variables.

This also provides a partial fix for #138

@freemo Just made one last fix, this is now ready for merging. Previous commit didn't support I_ALOAD. It turns out that local variable arguments like are handled differently, that is, if array is the first argument func(arr, index) then I_ALOAD_0 is used. However for the second argument in func(index, arr) then I_ALOAD_1 is used, if func(index, indexA, arr) then I ALOAD_2 is used and so on, until index 4, at index 4, I_ALOAD is used instead, which supports non-const indexing (index > 3), so that the instruction has an additional field for specifying an 8 bit index of the local variable argument.
