nvptx will be the first port to use BImode and have 
STORE_FLAG_VALUE==-1. That has exposed a bug in combine where we can end 
up calling num_sign_bit_copies for a BImode value. However, the return 
value is always 1 in that case, so it doesn't tell us anything and is 
going to be misinterpreted by the caller.

Bootstrapped and tested on x86_64-linux, together with the other 
patches.  Ok?
