    - New сardmarking write barrier handles large objects and normal objects in a similar fashion (no more additional space for pointer tracking is required, no conditional branches in WB code).
    - Changes to enable oldspaces iteration without maps decoding:
    -- layout change for FixedArrays: length is stored as a smis (initial patch by
    Kevin Millikin)
    -- layout change for SharedFunctionInfo: integer fields are stored as smi on
    arm, ia32 and rearranged on x64.
    -- layout change for String: meaning of LSB bit is fliped (1 now means hash not
    computed); on x64 padding is added.
    -- layout of maps is _not_ changed. Map space is currently iterated in a special
    way.
