dwarf2out.c (expand_builtin_dwarf_reg_size): Look at all ranges when generating the decision tree for the general case.

	* dwarf2out.c (expand_builtin_dwarf_reg_size): Look at all ranges
	when generating the decision tree for the general case.
	* config/m68k/m68k.h (HARD_REGNO_MODE_OK): Don't accept modes
	wider that 12 bytes in fpu regs or wider than 8 byte in fpa regs.
