Summary: Replace the 32-bit allocator with a 64-bit one with a non-constant base address, and reduce both the number of size classes and the maximum size of per-thread caches. As measured on [1], this reduces average weighted memory overhead (MaxRSS) from 26% to 12% over stock android allocator. These numbers include overhead from code instrumentation and hwasan shadow (i.e. not a pure allocator benchmark). This switch also enables release-to-OS functionality, which is not implemented in the 32-bit allocator. I have not seen any effect from that on the benchmark.
