A bug fix discovered while working on the other patches. Previously,
this was a comparison of a GET_MODE_BITSIZE vs a GET_MODE_SIZE value.
After the other patches, it's GET_MODE_PRECISION vs GET_MODE_SIZE, which
is just as wrong, so change it.

* rtlanal.c (nonzero_bits1): Don't compare GET_MODE_SIZE against
	a bitsize.
