Simplify pad_below implementation
This patch simplifies the alignment calculations in pad_below.
The first arm of the "if" was:
- taking GET_MODE_BITSIZE (always equal to GET_MODE_SIZE * BITS_PER_UNIT),
- rounding up to the next multiple of PARM_BOUNDARY
- converting bits to bytes and
- subtracting the GET_MODE_SIZE
so was in effect calculating the number of bytes needed to round
GET_MODE_SIZE up to (PARM_BOUNDARY / BITS_PER_UNIT). That can be
done more directly as -size & (align - 1), which is easier to
convert to variable-sized modes.
