[RFA]rs6000-tdep.c: add nofp register set

[Elena Zannoni]

Some ppc variants (855, 823) don't have a floating point unit.
I've just added a register set to be used for such variants.

2000-04-17  Elena Zannoni  <ezannoni@redhat.com>

	* rs6000-tdep.c (COMMON_UISA_NOFP_REGS): New macro.
	(registers_powerpc_nofp): New register set for processors
	without floating point unit.
