RFR: 8328316: Finisher cannot emit if stream is sequential and integrator returned false

Wed Mar 20 20:24:31 UTC 2024

Adds differentiation between direct and transitive short circuiting which could prevent pushing downstream in the finisher for built-ins that were not `collect()`.

Creating this as a draft PR for now, just need to run some benchmarks to validate no significant regressions first.
