[PATCH] RISC-V: Fix V_WHOLE && V_FRACT iterator requirement

[juzhe . zhong]

From: Juzhe-Zhong <juzhe.zh...@rivai.ai>

This patch fixes the requirement of V_WHOLE and V_FRACT.
E.g. VNx8QI in V_WHOLE has no requirement which is incorrect.
     Actually, VNx8QI should be whole(full) mode when TARGET_MIN_VLEN < 128
     since when TARGET_MIN_VLEN == 128, VNx8QI is e8mf2 which is fractional
     vector.

gcc/ChangeLog:

        * config/riscv/vector-iterators.md: Fix requirement.
