The goal is to do this in st_validate_state:
    while (dirty)
       atoms[u_bit_scan(&dirty)]->update(st);

That implies that atoms can't specify which flags they consume.
There is exactly one ST_NEW_* flag for each atom. (58 flags in total)

There are macros that combine multiple flags into one for easier use.

All _NEW_* flags are translated into ST_NEW_* flags in st_invalidate_state.
st/mesa doesn't keep the _NEW_* flags after that.

torcs is 2% faster between the previous patch and the end of this series.

Could we just use the u_bit_scan64() function and void the hi/lo split?

Otherwise, the series looks good to me.  Nice clean-ups!
