[PATCH, rs6000] Remove the (no longer used) BTC defines.

Browse source 
These defines are no longer used once the rs6000 built-in
reworks were completed.   Time to remove them.

There was a reference to RS6000_BTC_SPECIAL in a TODO comment
in rs6000-builtins.def.  That comment remains, but I have updated
the comment to refer to "SPECIAL" processing, instead of having it
refer directly to the _BTC_SPECIAL macro.

	* config/rs6000/rs6000-builtins.def: Rephrase
