Detailed Description

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.
