commit 832cdeeccb063073ba2893ec63060773fc8b98ae
Author: Jin Ma <jinma@linux.alibaba.com>

    RISC-V: Add vector mask instructions for T-Head VECTOR vendor extension
    
    T-Head has a range of vendor-specific instructions. Therefore
    it makes sense to group them into smaller chunks in form of
    vendor extensions.
    
    This patch adds mask instructions for the "XTheadVector"
    extension. The 'th' prefix and the "XTheadVector" extension
    are documented in a PR for the RISC-V toolchain conventions ([1]).
