(mips_gdbarch_init): Use MIPS_A0_REGNUM instead of A0_REGNUM,
MIPS_RA_REGNUM instead of RA_REGNUM, MIPS_T9_REGNUM instead of
T9_REGNUM, MIPS_V0_REGNUM instead of V0_REGNUM, MIPS_ZERO_REGNUM
instead of ZERO_REGNUM, MIPS32_SIZE_INSN instead of MIPS_INSTLEN
and MIPS16_INSN_SIZE instead of MIPS16_INSTLEN.
(mips_dump_tdep): Don't print A0_REGNUM, RA_REGNUM,
T9_REGNUM, V0_REGNUM, ZERO_REGNUM, MIPS_INSTLEN and
MIPS16_INSTLEN.  Use MIPS_A0_REGNUM instead of A0_REGNUM.

(mipsnbsd_get_longjmp_target): Use MIPS_A0_REGNUM instead of
A0_REGNUM.
* mipsnbsd-nat.c: Include "mips-tdep.h".
(getregs_supplies): Use MIPS_ZERO_REGNUM instead of ZERO_REGNUM.
* Makefile.in (mipsnbsd-nat.o): Update dependencies.

/* Figure out where the longjmp will land. We expect that we have
just entered longjmp and haven't yet setup the stack frame, so
the args are still in the argument regs. A0_REGNUM points at the
