TLSF currently uses only 4-byte alignment on 32-bit platforms, which isn't enough for ldrd/strd on ARMv7. This series reworks TLSF a bit, so we always have at least 8 byte alignment. dlmalloc already has 8 byte alignment minimum, so nothing to do there. While this fixes real issues like what Enrico ran into, I'd suggest we only this be taken into next only after v2022.10.0 is tagged, so this can get some more testing exposure in the mean time.
