[X86][Atom] Fix FP uops + port usage

Both ports are required in most cases. Update the uops counts + port usage based off the most recent llvm-exegesis captures (PR36895) and what Intel AoM / Agner / InstLatX64 reports as well.

Noticed while trying to improve fp costs for vectorization via the D103695 helper script.
