Explicit argument can be lambda

Reports method calls that accept a non-trivial expression and can be replaced with an equivalent method call which accepts a lambda instead.

Converting an expression to a lambda ensures that the expression won't be evaluated if it's not used inside the method. For example, optional.orElse(createDefaultValue()) can be converted to optional.orElseGet(this::createDefaultValue).

This inspection depends on the Java feature 'Lambda expressions', which is available since Java 8.
