With\nthese RosAlloc changes, the benchmark score no longer regresses after\nwe enable the flag.\n\nChanged Run::AllocSlot to only have one mode of allocation. The new\nmode is finding the first free bit in the bitmap. This was\npreviously the slow path but is now the fast path. Some optimizations\nwhich enabled this include always having the alloc bitmap bits which\ncorrespond to invalid slots be set to 1. This prevents us from needing\na bound check since we will never end up allocating there.\n\nChanged revoking thread local buffer to point to an invalid run. The\ninvalid run is just a run which always has all the allocation bits set\nto 1. When a thread attempts to do a thread local allocation from here\nit will always fail and go slow path. This eliminates the need for a\nnull check for revoked runs.\n\nChanged zeroing of memory to happen during free, AllocPages should\nalways return zeroed memory.

For a 100 MS GC\nthis used at least 16 * (100 / .005) bytes of storage inside of the\nhistogram data structure. If you consider the 3 different GC types,\nand each timing logger having its own histogram its easy to see\nhow memory used was significant.\n\nWe now have an upper bound on the number of buckets (default 100).\nWhen we hit the upper bound we simply combine adjacent buckets\ntogether. This reduces the total number of buckets by a factor of\n2, while increasing the bucket size by a factor of 2. This means\nthat we may lose a slight amount of precision, but the confidence\nintervals remain nearly as useful.\n\nTotal unknown memory (occam-svelte):\nBefore: 45648 kB:\nAfter: 33304 kB\n\nThere are probably still some additional optimizations which can be\ndone as disabling histograms altogether reduces the memory used by\nanother ~2mB.\n\nA bit of other cleanup in image_space.cc and dlmalloc_space.cc.\n\nBug: 9967927\n\nChange-Id: I87bb6fe4a3e0e790f104abf3cf07f67677cd7ab3\n"
