Hi,
This patch fixes PR61446.  The problem appears when we insert value copies 
after transformations. We use the widest extension mode met in a chain, but it 
may be wider than original destination register size.  This patch checks it and 
use smaller mode if required.

Bootstrapped and tested on linux-x86_64.

Does it look OK?

Thanks,
Ilya

That seems wrong.   Something should have rejected this earlier.  Let me 
take a looksie.
