[PAHOLE]: Combine bitfields and demote the ones that have more bits than needed
...
This allows us to save 4 more bytes in struct task_struct, for instance, now we
need to combine whole bitfields with other fields if some bitfield has a size
less than sizeof(void *) and there is a suitable hole.

[PAHOLE]: Introduce --reorganize
...
Reorganizes structs with holes as non disruptively as possible to combine
holes, possibly reducing the struct size.
It doesn't yet combines bit holes, but will.
And will suggest type demotion in the bitfields case i.e. if there is a integer
(4) bytes bitfield that could fit on an short int bitfield or on a char
bitfield, it'll do just that 8)
