There was a patch to change GET_CODE(..) == CONST_INT to CONST_INT_P,
and in one instance this was done incorrectly, leaving only a plain
GET_CODE without any comparison. I've committed the following as
obvious after testing on x86_64-linux.

* simplify-rtx.c (simplify_unary_operation_1): Use CONST_INT_P in
shift simplification where it was intended.
