[PATCH] RISC-V: Add "m_" prefix for private member

[juzhe . zhong]

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

Since the current framework is hard to maintain and
hard to be used in the future possible auto-vectorization patterns.

We will need to keep adding more helpers and arguments during the 
auto-vectorization supporting. We should refactor the framework
now for the future use since the we don't support too much auto-vectorization
patterns for now.

Start with this simple patch, this patch is adding "m_" prefix for private the 
members.

gcc/ChangeLog:

        * config/riscv/riscv-v.cc: Add "m_" prefix.
