Attempting to use the existing FORK_OPT opcode resulted in difficulty knowing when to pop an error message off the stack and when not to. This commit makes DESTRUCTURE_ALT a real opcode that is identical to FORK_OPT, except for never pushing the error message onto the stack when continuing from an error backtrack. Some small changes were necessary to the DUP/POP behavior surrounding destructuring to accomodate this.
