V850 breakpoint support

The attached patches are required in order to support breakpoint
on the NEC/V850 (not V850e). The major complication is that this
processor has variable length instructions (16, 32 bits) and the
"official" illegal instruction [normally used for breakpoints] is
32 bits. Since GDB doesn't handle this very well, an alternate
solution involving a useless instruction "br *" was chosen.
