Ignore Thumb; I'm not sure anybody would want to run LuaJIT on a
Thumb-only device (like a Cortex M3).  ARM's hardware FP has always
left something to be desired, so a combined approach like Asko's
integer patch might be a solution.  And for the most part (excluding
floating point), it should be quite easy to produce code that will run
on both ARMv3 and 4 and ARMv7.
