[X86][tablgen] Add three entries manually into the memory folding table

```
{X86::MOVLHPSrr,X86::MOVHPSrm}
{X86::VMOVLHPSZrr,X86::VMOVHPSZ128rm}
{X86::VMOVLHPSrr,X86::VMOVHPSrm}
```

Each of the three pairs has different mnemonic, so we have to add it
manually. This is a follow-up patch for D122477.
