Michael Anthony Knyszek 9ac1ee2d46 runtime: track the amount of scannable allocated stack for the GC pacer This change adds two fields to gcControllerState: stackScan, used for pacing decisions, and scannableStackSize, which directly tracks the amount of space allocated for inuse stacks that will be scanned. scannableStackSize is not updated directly, but is instead flushed from each P when at an least 8 KiB delta has accumulated. This helps reduce issues with atomics contention for newly created goroutines. Stack growth paths are largely unaffected.
