This patch set adds four vendor-specific ISA extensions from SiFive:
"xsfvqmaccdod", "xsfvqmaccqoq", "xsfvfnrclipxfqf", and "xsfvfwmaccqqq".
Additionally, a new hwprobe key, RISCV_HWPROBE_KEY_VENDOR_EXT_SIFIVE_0,
has been added to query which SiFive vendor extensions are supported on
the current platform.
