Helpers and refactorings to prepare for interpreter optimizations (x64)

- Add data structure offsets that will be used in assembly code.
- Be explicit about a stack overflow in a fault handler.
- Move assembly helper code in asm_support so interpreter can use it.
- Support putting literals in InterpreterCache.
- Fix artHandleFillArrayDataFromCode for x64.
