FP vector extension test fails for skylake-avx512 CPU. Works fine for sapphirerapids CPU.
```
$ llc bugpoint-reduced-simplified.ll -mcpu=skylake-avx512
llc: /localdisk/ilyaenko/llvm-project/llvm/include/llvm/CodeGen/ValueTypes.h:307: llvm::MVT llvm::EVT::getSimpleVT() const: Assertion `isSimple() && "Expected a SimpleValueType!"' failed.
```
Simplified reproducer:
