RFR: 8373695: G1: Using a value near integer max for ActiveProcessorCount causes fatal crash [v2]

Fri Dec 19 11:42:05 UTC 2025

> G1ConcRefinementThreads default value depends on ParallelGCThreads which in turn may depend on ActiveProcessorCount. These have different ranges that are valid. Patch will ensure argument setup code never try to assign a value larger than what G1ConcRefinementThreads expects.
