runtime: move malloc stats into consistentHeapStats This change moves the mcache-local malloc stats into the consistentHeapStats structure so the malloc stats can be managed consistently with the memory stats. The one exception here is tinyAllocs for which moving that into the global stats would incur several atomic writes on the fast path. Microbenchmarks for just one CPU core have shown a 50% loss in throughput. Since tiny allocation counnt isn't exposed anyway and is always blindly added to both allocs and frees, let that stay inconsistent and flush the tiny allocation count every so often.
