From: Pan Li <pan2...@intel.com>
Add asm dump check and for vec_duplicate + vadd.vv combine to vadd.vx.
The late-combine will not take action when GR2VR cost is 1.
The below test suites are passed for this patch.
* The rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/vx_vf/vx_vadd-2-i16.c: New test.
* gcc.target/riscv/rvv/autovec/vx_vf/vx_vadd-2-i32.c: New test.
* gcc.target/riscv/rvv/autovec/vx_vf/vx_vadd-2-i64.c: New test.
* gcc.target/riscv/rvv/autovec/vx_vf/vx_vadd-2-i8.c: New test.
* gcc.target/riscv/rvv/autovec/vx_vf/vx_vadd-2-u16.c: New test.
