* mips-tdep.c (mips_ecoff_reg_to_regnum): Rename to

	mips_dwarf_dwarf2_ecoff_reg_to_regnum().
	(mips_dwarf_dwarf2_ecoff_reg_to_regnum, mips_stab_reg_to_regnum):
	Do range checks on register number obtained from debugging info.
	(mips_gdbarch_init): Call set_gdbarch_dwarf_reg_to_regnum() and
	set_gdbarch_dwarf2_reg_to_regnum().  Adjust call of
	set_gdbarch_ecoff_reg_to_regnum() to account for new name of
	mapping function.
	(do_fp_register_row): Fix typo which caused double type to be
	used when attempting to unpack a float.
