[PATCH] RISC-V: Remove unit-stride store from ta attribute

[juzhe . zhong]

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

Since store instructions doesn't care about tail policy, we remove 
vste from "ta" attribute. Hence, we could have more fusion chances
and better optimization.

gcc/ChangeLog:

        * config/riscv/vector.md: Remove vste.
