locking/atomic, alpha: Use s64 for atomic64

Browse Source 
As a step towards making the atomic64 API use consistent types treewide,
let's have the alpha atomic64 implementation use s64 as the underlying
type for atomic64_t, rather than long, matching the generated headers.

As atomic64_read() depends on the generic defintion of atomic64_t, this
still returns long. This will be converted in a subsequent patch.

Otherwise, there should be no functional change as a result of this
patch.
