  [X86][SLM] Fix DIVPD/DIVPS/RCPPS/RSQRTPS/SQRTPD/SQRTPS/DPPD/DPPS uops, latency and throughput

The packed variants of the instructions had been modelled as the same as the scalar variants.

Reported during a run of llvm-exegesis on a cheap SLM box and matches what Agner / InstLatX64 report as well.
