Logical Not op broken

The following script generates this error: `ParseFail(InternalError("Operation has invalid argument types: [Argument::Object(operand)], in src\\aml\\mod.rs:1945"))`

```
DefinitionBlock("", "DSDT", 1, "RSACPI", "LOGICNOT", 1) {
    Method (MAIN, 0, NotSerialized) {
        Local0 = !1
        Return (Local0)
    }
}
```

This happens whether it's the `!` or `LNot()` operations.
