[ruby/yarp] Introduce MatchLastLineNode and InterpolatedMatchLastLineNode
These are replacements for regular expressions when they are used alone as the predicate of a conditional. That's because they are significantly different from a regular expression because they are not evaluated for truthyness, but instead evaluated as a match against the last line read by an IO object.
