CheckOptionalEmptiness disregards initial value, fallback value

From the history of CheckOptionalEmptiness I'm not entirely certain which exact issues it is intended to protect against but I ran into a surprise with j.u.Optional::or that led me to map out a number of false positive warnings. These seem to revolve around

1. the initial value passed to an Optional factory is ignored
2. fallback providers are not recognized

Both cases fail with [NullAway] Invoking get() on possibly empty Optional o

Some of these look like #557 but I don't see other related issues.

All of my cases for posterity:

Object value;
Optional<Object> o;

if (o.isPresent()) {
    value = o.get(); // true negative
} else {
    value = o.get(); // true positive

value = o.orElseThrow(); // true negative
value = o.orElseThrow(RuntimeException::new); // true negative
