Interpreter.
The opcodes filled-new-array and packed-switch aren't implemented but
are trivial given that they are variants of implemented opcodes.
Refactor Field::Get routines to take the declaring class in the case of
static field accesses. This avoids a check on every use of a field.
Refactor arg array builder to be shared by JNI invokes and invocations
into the interpreter.
Fix benign bug in const decoding in the verifier.
