target/m68k: manage 680x0 stack frames
680x0 manages several stack frame formats:
- format 0: four-word stack frame
- format 1: four-word throwaway stack frame
- format 2: six-word stack frame
- format 3: Floating-Point post-instruction stack frame
- format 4: eight-word stack frame
- format 7: access-error stack frame
