  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 reductions instructions for the "XTheadVector"
extension. The 'th' prefix and the "XTheadVector" extension
are documented in a PR for the RISC-V toolchain conventions ([1]).

	reductions instructions.
	* testsuite/gas/riscv/x-thead-vector.s: Likewise.

include/ChangeLog:

	* opcode/riscv-opc.h (MATCH_TH_VREDSUMVV): New.

opcodes/ChangeLog:

	* riscv-opc.c: Likewise.
