Calculate the format for CONST_DOUBLE. We need as many slots as are necessary to overlay a REAL_VALUE_TYPE on them. This could be as many as four (32-bit HOST_WIDE_INT, 128-bit REAL_VALUE_TYPE). A number of places assume that there are always at least two 'w' slots in a CONST_DOUBLE, so we provide them even if one would suffice.
Describes the properties of the specific target format in use.
