patch I'm testing

Patch to reject the problematic insns by adding a predicate to detect them and
check it in the conditions for the *movsi_m68k and *movsi_m68k2 insns.  If
someone knows of a better way please let me know.  Only lightly tested so far,
but seems to do the right thing on the test case in #c11.

I'm going to bootstrap and regression test this natively on Aranym, but that
will take weeks as I need to establish a current baseline first.
