a3d9ca92 - [RISCV] Make the vsll->vadd intrinsic pattern support tail undisturbed intrinsics.

[RISCV] Make the vsll->vadd intrinsic pattern support tail undisturbed intrinsics. We convert a shift left by 1 to vadd. But we only did it for tail agnostic or masked intrinsics. This extends it to tail undisturbed unmasked intrinsics.
