This patch is part of the Mips CFI work started by Kevin Buettner.
As requested, I am splitting the previously posted patch into multiple
small patches.

To get DWARF2 CFI unwinding to work, SP_REGNUM needs to refer to the
cooked register number, not the raw register number.

        * config/mips/tm-mips.h (SP_REGNUM): Delete define.
	* mips-tdep.h (MIPS_SP_REGNUM): Define.
	* mips-tdep.c (mips_gdbarch_init): Set SP_REGNUM via call
	to set_gdbarch_sp_regnum().  Use cooked register number.
        (SP_REGNUM): Replace all occurrences with MIPS_SP_REGNUM.
