Add "Printing" mode
Idea: when printing, we should be more lenient about conditions that
would otherwise cause an assertion failure, because we want to avoid
triggering further assertions while diagnosing previous errors. As a start
we generalize an assertion that RefinedTypes cannot be created after erasure.
This gets triggered when playing around with printing lambdas at erasure time
(see following commit): erasure runs at phase erasure + 1, so ctx.erasedTypes is true,
but we might still want to print lambdas then, and printing lambdas will create new
refined types as of next commit.
