Fix table access bug where index wasn't required to be initialized.

* Initialized `byte table` values need not have all 256 bytes initialized.
|
| 8 | 8 |
* Constraints for `vector` type come immediately after the type, not the variable.
|
| 9 | 9 |
* `vector table` storage, and ability to copy vectors in and out of same.
|
|
10 |
* Fixed bug where index register wasn't required to be initialized before table access.
