* i386-tdep.c (i386_num_register_names): New variable. 

(i386_num_mmx_regs): Renamed from mmx_num_regs.
(MM0_REGNUM): Remove redundant parentheses in define.
(i386_mmx_regnum_p): Use i386_mmx_regnum instead of mmx_num_regs.
(i386_fp_regnum_p, i386_fpc_regnum_p, i386_sse_regnum_p,
i386_mxcsr_regnum_p): Remove redundant parentheses.
(i386_register_name): Use i386_num_register_names.
