Treat Boolean.False as false primitive

[Akirathan]

Fixes #6076

Pull Request Description

Treat Boolean.False and Boolean.True as the corresponding primitives. Now, Boolean.False == False returns true.

Important Notes

False and True constructs, that are converted to ConstructorNode during Truffle codegen, are handled specially in ConstructorNode. The easiest fix was to implement a similar special handling in QualifiedAccessorNode, although not the cleanest one.

A better solution would be to provide transformation of Boolean.True IR to a true literal in ApplicationSaturation compiler pass. But ApplicationSaturation pass does not handle True. Moreover, for our case, it is unnecessarily complicated.

@hubertp I hope it is not a problem to replace this with log.info. I did it because locally, I connect to the SBT server via socket, and it sends me back only messages from logging, and this message was just discarded.
