* config/m68k/tm-m68k.h: Rearrange code so macros not in the
gdbarch vector are at the top.
(NUM_REGS): Remove.
(FP_REGNUM, SP_REGNUM, PS_REGNUM, PC_REGNUM, FP0_REGNUM): Remove.
(FRAME_ARGS_ADDRESS): Remove.
(FRAME_LOCALS_ADDRESS): Remove.
(FRAME_NUM_ARGS): Remove.
(FRAME_ARGS_SKIP): Remove.
* m68k-tdep.c (enum): Add eumeration of special register numbers.
(m68k_gdbarch_init): Add gdbarch initializations for macros
undefined in tm-m68k.h
