[PATCH] RISC-V: Fix RVV_VLMAX

This patch fixes memory hog found in SPEC2017 wrf benchmark which caused by RVV_VLMAX since RVV_VLMAX generate brand new rtx by gen_rtx_REG (Pmode, X0_REGNUM) every time we call RVV_VLMAX, that is, we are always generating garbage and redundant (reg:DI 0 zero) rtx. After this patch fix, the memo
