(TARGET_SWITCHES): Group all floating point options.

Browse Source 
When an fp option is selected, unset bits used for other mutually
exclusive fp options.
(OVERRIDE_OPTIONS): No longer need special case for SUPPORT_SUN_FPA, as the
bits used for 68881 and SKY are cleared by new entries in TARGET_SWITCHES.
