In breakpoint(), use a different immediate to make sure we can
distinguish between debugger inserted breakpoints and fixed
breakpoints. While here, make sure the break instruction never
ends up in the last slot of a bundle by forcing it to be an
M-unit instruction. This makes it easier for use to skip over
it.
