Changes in this patch:

- Minor changes to the LowerVECREDUCE_SEQ_FADD function added by @cameron.mcinally to also work for scalable types
- Added TableGen patterns for FP reductions with unpacked types (nxv2f16, nxv4f16 & nxv2f32)
- Asserts added to expandFMINNUM_FMAXNUM & expandVecReduceSeq for scalable types
