[X86] Handle VPMADD52L for smaller min-legal-vector-width (#183250)
There is crash as below https://godbolt.org/z/qdE1EE4Y9, After
https://github.com/llvm/llvm-project/pull/171760 .
```
ReplaceNodeResults: t32: v8i64 = X86ISD::VPMADD52L t10, t22, t2
Do not know how to custom type legalize this operation!
```
For ```"min-legal-vector-width"="512"```, it works fine, but for smaller
value it is crash.
