* i386-tdep.h (FPC_REGNUM, FCTRL_REGNUM, FSTAT_REGNUM, FTAG_REGNUM)

(FISEG_REGNUM, FIOFF_REGNUM, FOSEG_REGNUM, FOOFF_REGNUM)
(FOP_REGNUM, XMM0_REGNUM, MXCSR_REGNUM): Remove macros.
(i386_frameless_signal_p): Remove prototype.
* i386-linux-nat.c (GETFPREGS_SUPPLIES): Remove macro.
(GETFPXREGS_SUPPLIES): Define using I386_ST0_REGNUM and
I386_SSE_NUM_REGS.
* i386-nto-tdep.c (i386nto_supply_gregset): Use I386_NUM_GREGS
instead of FP0_REGNUM.
(i386nto_regset_id): Use I386_NUM_GREGS and I386_NUM_FREGS instead
of FP0_REGNUM and FPC_REGNUM.
