b48e5f0f - [RISCV][VLOPT] Add Vector FP instructions to getOperandInfo (#121609)

[RISCV][VLOPT] Add Vector FP instructions to getOperandInfo (#121609) Although we cannot reduce the VL of these instructions (i.e. add to isSupported) we can add them to getOperandInfo to enable optimization where the FP vector instruction are users. Most of the instructions are covered by existing tests, and I added tests for the narrowing conversions because I was a little unsure whether the dest or the source was 2*SEW and 2*LMUL.
