simplify GET/SETFIELD() use, add MASK_TO_LSH()
Currently, the GETFIELD() and SETFIELD() macros require the user to define
both the _MASK and the _LSH of the field. However, the shift of the field
is trivially determinable and there is no reason it needs to be specified
by the user.
Add MASK_TO_LSH() macro, which determines the shift of a given mask.
Change GETFIELD() and SETFIELD() to use MASK_TO_LSH() to determine the
shift of the specified mask, instead of requiring it to be specified by
the user.
