Target FP: Remove unused floating-point routines

This patch removes the following routines, which now have no remaining
users in GDB:
 - extract_typed_floating
 - store_typed_floating
 - convert_typed_floating
 - decimal_from_doublest
 - decimal_to_doublest
 - value_as_double
 - unpack_double
 - value_from_double
 - value_from_decfloat

This completes removal of DOUBLEST from all files except doublest.{c,h}
and target-float.c.
