Fix PR rust/20110

PR rust/20110 concerns the type of an integer constant that is too
large for "i32", the default integer type.  This patch changes the
type of such a constant to i64.  This is important because such values
are often addresses, so truncating them by default is unfriendly.

Built and regtested on x86-64 Fedora 23.
