Change subject: Remove AMD Opteron Rev E workaround from atomicops ...................................................................... Remove AMD Opteron Rev E workaround from atomicops Impala doesn't run on Opteron Rev E because those CPUs don't support SSSE3. So let's not pay the price of this cmp/branch on the atomics path (which is used by our SpinLock, and I plan to make our Atomic class use these functions in a future change). Note that gperfutil also removed this RevE workaround since these CPUs are getting old and apparently many kernels don't have the workaround anyway. Let's call the init function for atomicops, even though it's basically a no-op for 64-bit mode (since these features are always available). But this future proofs the code a bit better.
