* ppc-tdep.h (struct gdbarch_tdep): Add ev registers.

	* rs6000-tdep.c (rs6000_register_virtual_type): Return 64 bit
	vector type for ev registers.
	(e500_pseudo_register_read): New function.
	(e500_pseudo_register_write): New function.
	(e500_dwarf2_reg_to_regnum): New function.
	(PPC_UISA_NOFP_SPRS): New macro.
	(PPC_EV_REGS): New macro.
	(PPC_GPRS_PSEUDO_REGS): New macro.
	(registers_e500): New register set for e500.
	(variants): Add e500 variant.
	(rs6000_gdbarch_init): Move setting of pc, sp, fp regnums to
	before setting architectural dependent variations.  Initialize ev
	registers numbers.  Add case for e500 architecture.  Set the
	number of pseudo registers.
