Commit Message

Add support for boolean constraints (about nullness) in Contract annotations (#669)

For example, the following method will behave equivalently to guava `Preconditions.checkState` with regards to null checks:
```java
@Contract("false -> fail")
static void check(boolean pass) {
  if (!pass) throw new RuntimeException();
}
```

This implementation works in a couple of layers:
- Firstly, contracts with a single boolean resultin in failure are handled by inserting a conditional throw node inline following the annotated method. This provides support for complex boolean logic input validateion.
- Secondly, simple null equal-to and not-equal-to checks are handled by the existing ContractHandler. These don't support such complex inputs, however they are able to work correctly with boolean outputs rather than exclusively `fail` cases.

I've updated the ContractHandler to use more precise language around antecedent nullness, previously null antecedents were described as nullable where cases required null. Please let me know if I've misunderstood the logic, but re-framing the values helped me to understand the logic.
