Nia Waldvogel d01d0bb358 runtime (gc_blocks.go): make sweep branchless ...

Instead of looping over each block, we can use bit hacks to operate on an entire state byte.
I deinterleaved the state bits in order to enable these tricks.

Sweep used to count free/freed allocations/blocks.
I managed to move/remove all of these counters:
- The free space is now calculated in buildFreeRanges by adding the range lengths.
- ReadMemStats counts freed objects by subtracting live objects from allocated objects.
- gcFreedBlocks was never necessary because MemStats.HeapAlloc is the same as MemStats.HeapInUse.
