That's a good point. I added a check for this case - so if CONST_INT is
passed
we assume that mode is QI. But usually promoted value resides in a register,
so
we don't go over-conservative here.
Hmm, so if we use broadcast constant, then we won't end up having CONST_INT
here?
It is OK

Another follow-up to yesterday's patch. This one implements Richard's
suggestion of having an is_sign_extended trait to optimise cases where
excess upper bits are known to be signs rather than undefined.
The uses so far are:
* make to_shwi () equivalent to slow ()
* turn eq_p into a simple loop
