	* gcc.target/riscv/rvv/autovec: New directory
	for autovectorization tests.
	* gcc.target/riscv/rvv/autovec/loop-add-rv32.c: New
	test to verify code generation of vector add on rv32.
	* gcc.target/riscv/rvv/autovec/loop-add.c: New
	test to verify code generation of vector add on rv64.
	* gcc.target/riscv/rvv/autovec/loop-sub-rv32.c: New
	test to verify code generation of vector subtract on rv32.
	* gcc.target/riscv/rvv/autovec/loop-sub.c: New
	test to verify code generation of vector subtract on rv64.
