[JSC] Reduce more samples in DFG finalization
https://bugs.webkit.org/show_bug.cgi?id=272925
rdar://126711361
Reviewed by Keith Miller.
This patch attempts to remove more samples in DFG finalization, observed in
performance profiling.
1. Pass mustHandleValues via WTFMove to avoid additional allocation.
2. Clean up completeAllReadyPlansForVM to avoid taking a lock twice.
