Log Message:
Write code to handle unimplemented instructions trapped via SCB vector 0x18.
This may happen on machines missing parts of the instruction set (like
some floating point formats).
Only one new instruction added; POLYD, so that the libm assembly files can
be used on architectures missing that instruction.
Also; include emulation code if compile-time option INSN_EMULATE is defined
instead of trying to match on which cputype it is.
N.B. POLYD isn't fully implemented, just enough to make libm happy.
