Currently, riscv port supports vector operations which is fully compatible with vector extension 1.0 spec. And we have passed tier 1-4 tests with option "-XX:+UseVExt" with QEMU.
Due to lack of native environment which supports vector extension 1.0, we cannot carry out tests for vector operations on real hardware. So we decided to move port-specific option UseVExt from product to experimental for now, and rename UseVExt to UseRVV.
This also fixes some typos in comments, and removes unused v extension instructions.
The test results on HiFive Unleashed board (rv64imafdc) and NeZha D1 board (rv64imafdcvu) are in line with expectations.
