Craig Topper d21a43579e [LegalizeVectorOps][RISCV] Don't scalarize FNEG in ExpandFNEG if FSUB is marked Promote. ...

We have a special check that tries to determine if vector FP
operations are supported for the type to determine whether to
scalarize or not. If FP arithmetic would be promoted, don't unroll.

This improves Zvfhmin codegen on RISC-V.
